2017/08/21 - Amazon Route 53 - 15 updated api methods
Changes Update route53 client to latest version
{'ChangeBatch': {'Changes': {'ResourceRecordSet': {'Type': {'CAA'}}}}}
Creates, changes, or deletes a resource record set, which contains authoritative DNS information for a specified domain name or subdomain name. For example, you can use ChangeResourceRecordSets to create a resource record set that routes traffic for test.example.com to a web server that has an IP address of 192.0.2.44.
Change Batches and Transactional Changes
The request body must include a document with a ChangeResourceRecordSetsRequest element. The request body contains a list of change items, known as a change batch. Change batches are considered transactional changes. When using the Amazon Route 53 API to change resource record sets, Amazon Route 53 either makes all or none of the changes in a change batch request. This ensures that Amazon Route 53 never partially implements the intended changes to the resource record sets in a hosted zone.
For example, a change batch request that deletes the CNAME record for www.example.com and creates an alias resource record set for www.example.com. Amazon Route 53 deletes the first resource record set and creates the second resource record set in a single operation. If either the DELETE or the CREATE action fails, then both changes (plus any other changes in the batch) fail, and the original CNAME record continues to exist.
Traffic Flow
To create resource record sets for complex routing configurations, use either the traffic flow visual editor in the Amazon Route 53 console or the API actions for traffic policies and traffic policy instances. Save the configuration as a traffic policy, then associate the traffic policy with one or more domain names (such as example.com) or subdomain names (such as www.example.com), in the same hosted zone or in multiple hosted zones. You can roll back the updates if the new configuration isn't performing as expected. For more information, see Using Traffic Flow to Route DNS Traffic in the Amazon Route 53 Developer Guide.
Create, Delete, and Upsert
Use ChangeResourceRecordsSetsRequest to perform the following actions:
CREATE: Creates a resource record set that has the specified values.
DELETE: Deletes an existing resource record set that has the specified values.
UPSERT: If a resource record set does not already exist, AWS creates it. If a resource set does exist, Amazon Route 53 updates it with the values in the request.
Syntaxes for Creating, Updating, and Deleting Resource Record Sets
The syntax for a request depends on the type of resource record set that you want to create, delete, or update, such as weighted, alias, or failover. The XML elements in your request must appear in the order listed in the syntax.
For an example for each type of resource record set, see "Examples."
Don't refer to the syntax in the "Parameter Syntax" section, which includes all of the elements for every kind of resource record set that you can create, delete, or update by using ChangeResourceRecordSets.
Change Propagation to Amazon Route 53 DNS Servers
When you submit a ChangeResourceRecordSets request, Amazon Route 53 propagates your changes to all of the Amazon Route 53 authoritative DNS servers. While your changes are propagating, GetChange returns a status of PENDING. When propagation is complete, GetChange returns a status of INSYNC. Changes generally propagate to all Amazon Route 53 name servers within 60 seconds. For more information, see GetChange.
Limits on ChangeResourceRecordSets Requests
For information about the limits on a ChangeResourceRecordSets request, see Limits in the Amazon Route 53 Developer Guide.

string
[REQUIRED]
The ID of the hosted zone that contains the resource record sets that you want to change.
dict
[REQUIRED]
A complex type that contains an optional comment and the Changes element.
Comment (string) --
Optional: Any comments you want to include about a change batch request.
Changes (list) -- [REQUIRED]
Information about the changes to make to the record sets.
(dict) --
The information for each resource record set that you want to change.
Action (string) -- [REQUIRED]
The action to perform:
CREATE: Creates a resource record set that has the specified values.
DELETE: Deletes a existing resource record set.
UPSERT: If a resource record set doesn't already exist, Amazon Route 53 creates it. If a resource record set does exist, Amazon Route 53 updates it with the values in the request.
The values that you need to include in the request depend on the type of resource record set that you're creating, deleting, or updating:
Basic resource record sets (excluding alias, failover, geolocation, latency, and weighted resource record sets)
Name
Type
TTL
Failover, geolocation, latency, or weighted resource record sets (excluding alias resource record sets)
Name
Type
TTL
SetIdentifier
Alias resource record sets (including failover alias, geolocation alias, latency alias, and weighted alias resource record sets)
Name
Type
AliasTarget (includes DNSName, EvaluateTargetHealth, and HostedZoneId)
SetIdentifier (for failover, geolocation, latency, and weighted resource record sets)
ResourceRecordSet (dict) -- [REQUIRED]
Information about the resource record set to create, delete, or update.
Name (string) -- [REQUIRED]
The name of the domain you want to perform the action on.
Enter a fully qualified domain name, for example, www.example.com. You can optionally include a trailing dot. If you omit the trailing dot, Amazon Route 53 still assumes that the domain name that you specify is fully qualified. This means that Amazon Route 53 treats www.example.com (without a trailing dot) and www.example.com. (with a trailing dot) as identical.
For information about how to specify characters other than a-z, 0-9, and - (hyphen) and how to specify internationalized domain names, see DNS Domain Name Format in the Amazon Route 53 Developer Guide.
You can use the asterisk (*) wildcard to replace the leftmost label in a domain name, for example, *.example.com. Note the following:
The * must replace the entire label. For example, you can't specify *prod.example.com or prod*.example.com.
The * can't replace any of the middle labels, for example, marketing.*.example.com.
If you include * in any position other than the leftmost label in a domain name, DNS treats it as an * character (ASCII 42), not as a wildcard.
You can use the * wildcard as the leftmost label in a domain name, for example, *.example.com. You can't use an * for one of the middle labels, for example, marketing.*.example.com. In addition, the * must replace the entire label; for example, you can't specify prod*.example.com.
Type (string) -- [REQUIRED]
The DNS record type. For information about different record types and how data is encoded for them, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide.
Valid values for basic resource record sets: A | AAAA | CAA | CNAME | MX | NAPTR | NS | PTR | SOA | SPF | SRV | TXT
Values for weighted, latency, geolocation, and failover resource record sets: A | AAAA | CAA | CNAME | MX | NAPTR | PTR | SPF | SRV | TXT. When creating a group of weighted, latency, geolocation, or failover resource record sets, specify the same value for all of the resource record sets in the group.
Valid values for multivalue answer resource record sets: A | AAAA | MX | NAPTR | PTR | SPF | SRV | TXT
Values for alias resource record sets:
CloudFront distributions: A If IPv6 is enabled for the distribution, create two resource record sets to route traffic to your distribution, one with a value of A and one with a value of AAAA.
AWS Elastic Beanstalk environment that has a regionalized subdomain: A
ELB load balancers: A | AAAA
Amazon S3 buckets: A
Another resource record set in this hosted zone: Specify the type of the resource record set that you're creating the alias for. All values are supported except NS and SOA.
SetIdentifier (string) --
Weighted, Latency, Geo, and Failover resource record sets only: An identifier that differentiates among multiple resource record sets that have the same combination of DNS name and type. The value of SetIdentifier must be unique for each resource record set that has the same combination of DNS name and type. Omit SetIdentifier for any other types of record sets.
Weight (integer) --
Weighted resource record sets only: Among resource record sets that have the same combination of DNS name and type, a value that determines the proportion of DNS queries that Amazon Route 53 responds to using the current resource record set. Amazon Route 53 calculates the sum of the weights for the resource record sets that have the same combination of DNS name and type. Amazon Route 53 then responds to queries based on the ratio of a resource's weight to the total. Note the following:
You must specify a value for the Weight element for every weighted resource record set.
You can only specify one ResourceRecord per weighted resource record set.
You can't create latency, failover, or geolocation resource record sets that have the same values for the Name and Type elements as weighted resource record sets.
You can create a maximum of 100 weighted resource record sets that have the same values for the Name and Type elements.
For weighted (but not weighted alias) resource record sets, if you set Weight to 0 for a resource record set, Amazon Route 53 never responds to queries with the applicable value for that resource record set. However, if you set Weight to 0 for all resource record sets that have the same combination of DNS name and type, traffic is routed to all resources with equal probability. The effect of setting Weight to 0 is different when you associate health checks with weighted resource record sets. For more information, see Options for Configuring Amazon Route 53 Active-Active and Active-Passive Failover in the Amazon Route 53 Developer Guide.
Region (string) --
Latency-based resource record sets only: The Amazon EC2 Region where you created the resource that this resource record set refers to. The resource typically is an AWS resource, such as an EC2 instance or an ELB load balancer, and is referred to by an IP address or a DNS domain name, depending on the record type.
When Amazon Route 53 receives a DNS query for a domain name and type for which you have created latency resource record sets, Amazon Route 53 selects the latency resource record set that has the lowest latency between the end user and the associated Amazon EC2 Region. Amazon Route 53 then returns the value that is associated with the selected resource record set.
Note the following:
You can only specify one ResourceRecord per latency resource record set.
You can only create one latency resource record set for each Amazon EC2 Region.
You aren't required to create latency resource record sets for all Amazon EC2 Regions. Amazon Route 53 will choose the region with the best latency from among the regions that you create latency resource record sets for.
You can't create non-latency resource record sets that have the same values for the Name and Type elements as latency resource record sets.
GeoLocation (dict) --
Geo location resource record sets only: A complex type that lets you control how Amazon Route 53 responds to DNS queries based on the geographic origin of the query. For example, if you want all queries from Africa to be routed to a web server with an IP address of 192.0.2.111, create a resource record set with a Type of A and a ContinentCode of AF.
If you create separate resource record sets for overlapping geographic regions (for example, one resource record set for a continent and one for a country on the same continent), priority goes to the smallest geographic region. This allows you to route most queries for a continent to one resource and to route queries for a country on that continent to a different resource.
You can't create two geolocation resource record sets that specify the same geographic location.
The value * in the CountryCode element matches all geographic locations that aren't specified in other geolocation resource record sets that have the same values for the Name and Type elements.
You can't create non-geolocation resource record sets that have the same values for the Name and Type elements as geolocation resource record sets.
ContinentCode (string) --
The two-letter code for the continent.
Valid values: AF | AN | AS | EU | OC | NA | SA
Constraint: Specifying ContinentCode with either CountryCode or SubdivisionCode returns an InvalidInput error.
CountryCode (string) --
The two-letter code for the country.
SubdivisionCode (string) --
The code for the subdivision, for example, a state in the United States or a province in Canada.
Failover (string) --
Failover resource record sets only: To configure failover, you add the Failover element to two resource record sets. For one resource record set, you specify PRIMARY as the value for Failover; for the other resource record set, you specify SECONDARY. In addition, you include the HealthCheckId element and specify the health check that you want Amazon Route 53 to perform for each resource record set.
Except where noted, the following failover behaviors assume that you have included the HealthCheckId element in both resource record sets:
When the primary resource record set is healthy, Amazon Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the secondary resource record set.
When the primary resource record set is unhealthy and the secondary resource record set is healthy, Amazon Route 53 responds to DNS queries with the applicable value from the secondary resource record set.
When the secondary resource record set is unhealthy, Amazon Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the primary resource record set.
If you omit the HealthCheckId element for the secondary resource record set, and if the primary resource record set is unhealthy, Amazon Route 53 always responds to DNS queries with the applicable value from the secondary resource record set. This is true regardless of the health of the associated endpoint.
You can't create non-failover resource record sets that have the same values for the Name and Type elements as failover resource record sets.
For failover alias resource record sets, you must also include the EvaluateTargetHealth element and set the value to true.
For more information about configuring failover for Amazon Route 53, see the following topics in the Amazon Route 53 Developer Guide:
MultiValueAnswer (boolean) --
Multivalue answer resource record sets only: To route traffic approximately randomly to multiple resources, such as web servers, create one multivalue answer record for each resource and specify true for MultiValueAnswer. Note the following:
If you associate a health check with a multivalue answer resource record set, Amazon Route 53 responds to DNS queries with the corresponding IP address only when the health check is healthy.
If you don't associate a health check with a multivalue answer record, Amazon Route 53 always considers the record to be healthy.
Amazon Route 53 responds to DNS queries with up to eight healthy records; if you have eight or fewer healthy records, Amazon Route 53 responds to all DNS queries with all the healthy records.
If you have more than eight healthy records, Amazon Route 53 responds to different DNS resolvers with different combinations of healthy records.
When all records are unhealthy, Amazon Route 53 responds to DNS queries with up to eight unhealthy records.
If a resource becomes unavailable after a resolver caches a response, client software typically tries another of the IP addresses in the response.
You can't create multivalue answer alias records.
TTL (integer) --
The resource record cache time to live (TTL), in seconds. Note the following:
If you're creating or updating an alias resource record set, omit TTL. Amazon Route 53 uses the value of TTL for the alias target.
If you're associating this resource record set with a health check (if you're adding a HealthCheckId element), we recommend that you specify a TTL of 60 seconds or less so clients respond quickly to changes in health status.
All of the resource record sets in a group of weighted resource record sets must have the same value for TTL.
If a group of weighted resource record sets includes one or more weighted alias resource record sets for which the alias target is an ELB load balancer, we recommend that you specify a TTL of 60 seconds for all of the non-alias weighted resource record sets that have the same name and type. Values other than 60 seconds (the TTL for load balancers) will change the effect of the values that you specify for Weight.
ResourceRecords (list) --
Information about the resource records to act upon.
(dict) --
Information specific to the resource record.
Value (string) -- [REQUIRED]
The current or new DNS record value, not to exceed 4,000 characters. In the case of a DELETE action, if the current value does not match the actual value, an error is returned. For descriptions about how to format Value for different record types, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide.
You can specify more than one value for all record types except CNAME and SOA.
AliasTarget (dict) --
Alias resource record sets only: Information about the CloudFront distribution, AWS Elastic Beanstalk environment, ELB load balancer, Amazon S3 bucket, or Amazon Route 53 resource record set to which you're redirecting queries. The AWS Elastic Beanstalk environment must have a regionalized subdomain.
If you're creating resource records sets for a private hosted zone, note the following:
You can't create alias resource record sets for CloudFront distributions in a private hosted zone.
Creating geolocation alias resource record sets or latency alias resource record sets in a private hosted zone is unsupported.
For information about creating failover resource record sets in a private hosted zone, see Configuring Failover in a Private Hosted Zone in the Amazon Route 53 Developer Guide.
HostedZoneId (string) -- [REQUIRED]
Alias resource records sets only: The value used depends on where you want to route traffic:
CloudFront distribution
Specify Z2FDTNDATAQYW2.
Specify the hosted zone ID for the region in which you created the environment. The environment must have a regionalized subdomain. For a list of regions and the corresponding hosted zone IDs, see AWS Elastic Beanstalk in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference.
ELB load balancer
Specify the value of the hosted zone ID for the load balancer. Use the following methods to get the hosted zone ID:
Elastic Load Balancing table in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference: Use the value in the "Amazon Route 53 Hosted Zone ID" column that corresponds with the region that you created your load balancer in.
AWS Management Console: Go to the Amazon EC2 page, click Load Balancers in the navigation pane, select the load balancer, and get the value of the Hosted zone field on the Description tab.
Elastic Load Balancing API: Use DescribeLoadBalancers to get the value of CanonicalHostedZoneNameId. For more information, see the applicable guide:
Classic Load Balancer: DescribeLoadBalancers
Application Load Balancer: DescribeLoadBalancers
AWS CLI: Use describe-load-balancers to get the value of CanonicalHostedZoneNameID.
An Amazon S3 bucket configured as a static website
Specify the hosted zone ID for the region that you created the bucket in. For more information about valid values, see the Amazon Simple Storage Service Website Endpoints table in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference.
Another Amazon Route 53 resource record set in your hosted zone
Specify the hosted zone ID of your hosted zone. (An alias resource record set can't reference a resource record set in a different hosted zone.)
DNSName (string) -- [REQUIRED]
Alias resource record sets only: The value that you specify depends on where you want to route queries:
CloudFront distribution
Specify the domain name that CloudFront assigned when you created your distribution.
Your CloudFront distribution must include an alternate domain name that matches the name of the resource record set. For example, if the name of the resource record set is acme.example.com, your CloudFront distribution must include acme.example.com as one of the alternate domain names. For more information, see Using Alternate Domain Names (CNAMEs) in the Amazon CloudFront Developer Guide.
Elastic Beanstalk environment
Specify the CNAME attribute for the environment. (The environment must have a regionalized domain name.) You can use the following methods to get the value of the CNAME attribute:
AWS Management Console: For information about how to get the value by using the console, see Using Custom Domains with AWS Elastic Beanstalk in the AWS Elastic Beanstalk Developer Guide.
Elastic Beanstalk API: Use the DescribeEnvironments action to get the value of the CNAME attribute. For more information, see DescribeEnvironments in the AWS Elastic Beanstalk API Reference.
AWS CLI: Use the describe-environments command to get the value of the CNAME attribute. For more information, see describe-environments in the AWS Command Line Interface Reference.
ELB load balancer
Specify the DNS name that is associated with the load balancer. Get the DNS name by using the AWS Management Console, the ELB API, or the AWS CLI.
AWS Management Console: Go to the EC2 page, choose Load Balancers in the navigation pane, choose the load balancer, choose the Description tab, and get the value of the DNS name field. (If you're routing traffic to a Classic Load Balancer, get the value that begins with dualstack.)
Elastic Load Balancing API: Use DescribeLoadBalancers to get the value of DNSName. For more information, see the applicable guide:
Classic Load Balancer: DescribeLoadBalancers
Application Load Balancer: DescribeLoadBalancers
AWS CLI: Use describe-load-balancers to get the value of DNSName.
Amazon S3 bucket that is configured as a static website
Specify the domain name of the Amazon S3 website endpoint in which you created the bucket, for example, s3-website-us-east-2.amazonaws.com. For more information about valid values, see the table Amazon Simple Storage Service (S3) Website Endpoints in the Amazon Web Services General Reference. For more information about using S3 buckets for websites, see Getting Started with Amazon Route 53 in the Amazon Route 53 Developer Guide.
Another Amazon Route 53 resource record set
Specify the value of the Name element for a resource record set in the current hosted zone.
EvaluateTargetHealth (boolean) -- [REQUIRED]
Applies only to alias, failover alias, geolocation alias, latency alias, and weighted alias resource record sets: When EvaluateTargetHealth is true, an alias resource record set inherits the health of the referenced AWS resource, such as an ELB load balancer, or the referenced resource record set.
Note the following:
You can't set EvaluateTargetHealth to true when the alias target is a CloudFront distribution.
If the AWS resource that you specify in AliasTarget is a resource record set or a group of resource record sets (for example, a group of weighted resource record sets), but it is not another alias resource record set, we recommend that you associate a health check with all of the resource record sets in the alias target. For more information, see What Happens When You Omit Health Checks? in the Amazon Route 53 Developer Guide.
If you specify an Elastic Beanstalk environment in HostedZoneId and DNSName, and if the environment contains an ELB load balancer, Elastic Load Balancing routes queries only to the healthy Amazon EC2 instances that are registered with the load balancer. (An environment automatically contains an ELB load balancer if it includes more than one EC2 instance.) If you set EvaluateTargetHealth to true and either no EC2 instances are healthy or the load balancer itself is unhealthy, Amazon Route 53 routes queries to other available resources that are healthy, if any. If the environment contains a single EC2 instance, there are no special requirements.
If you specify an ELB load balancer in AliasTarget ``, ELB routes queries only to the healthy EC2 instances that are registered with the load balancer. If no EC2 instances are healthy or if the load balancer itself is unhealthy, and if ``EvaluateTargetHealth is true for the corresponding alias resource record set, Amazon Route 53 routes queries to other resources. When you create a load balancer, you configure settings for ELB health checks; they're not Amazon Route 53 health checks, but they perform a similar function. Do not create Amazon Route 53 health checks for the EC2 instances that you register with an ELB load balancer. For more information, see How Health Checks Work in More Complex Amazon Route 53 Configurations in the Amazon Route 53 Developer Guide.
We recommend that you set EvaluateTargetHealth to true only when you have enough idle capacity to handle the failure of one or more endpoints.
For more information and examples, see Amazon Route 53 Health Checks and DNS Failover in the Amazon Route 53 Developer Guide.
HealthCheckId (string) --
If you want Amazon Route 53 to return this resource record set in response to a DNS query only when a health check is passing, include the HealthCheckId element and specify the ID of the applicable health check.
Amazon Route 53 determines whether a resource record set is healthy based on one of the following:
By periodically sending a request to the endpoint that is specified in the health check
By aggregating the status of a specified group of health checks (calculated health checks)
By determining the current state of a CloudWatch alarm (CloudWatch metric health checks)
For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy.
The HealthCheckId element is only useful when Amazon Route 53 is choosing between two or more resource record sets to respond to a DNS query, and you want Amazon Route 53 to base the choice in part on the status of a health check. Configuring health checks only makes sense in the following configurations:
You're checking the health of the resource record sets in a group of weighted, latency, geolocation, or failover resource record sets, and you specify health check IDs for all of the resource record sets. If the health check for one resource record set specifies an endpoint that is not healthy, Amazon Route 53 stops responding to queries using the value for that resource record set.
You set EvaluateTargetHealth to true for the resource record sets in a group of alias, weighted alias, latency alias, geolocation alias, or failover alias resource record sets, and you specify health check IDs for all of the resource record sets that are referenced by the alias resource record sets.
For geolocation resource record sets, if an endpoint is unhealthy, Amazon Route 53 looks for a resource record set for the larger, associated geographic region. For example, suppose you have resource record sets for a state in the United States, for the United States, for North America, and for all locations. If the endpoint for the state resource record set is unhealthy, Amazon Route 53 checks the resource record sets for the United States, for North America, and for all locations (a resource record set for which the value of CountryCode is *), in that order, until it finds a resource record set for which the endpoint is healthy.
If your health checks specify the endpoint only by domain name, we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com. For the value of FullyQualifiedDomainName, specify the domain name of the server (such as us-east-2-www.example.com), not the name of the resource record sets (example.com).
For more information, see the following topics in the Amazon Route 53 Developer Guide:
TrafficPolicyInstanceId (string) --
When you create a traffic policy instance, Amazon Route 53 automatically creates a resource record set. TrafficPolicyInstanceId is the ID of the traffic policy instance that Amazon Route 53 created this resource record set for.

{'TrafficPolicy': {'Type': {'CAA'}}}
Creates a new version of an existing traffic policy. When you create a new version of a traffic policy, you specify the ID of the traffic policy that you want to update and a JSON-formatted document that describes the new version. You use traffic policies to create multiple DNS resource record sets for one domain name (such as example.com) or one subdomain name (such as www.example.com). You can create a maximum of 1000 versions of a traffic policy. If you reach the limit and need to create another version, you'll need to start a new traffic policy.

{'StartRecordType': {'CAA'}}
Response {'NextRecordType': {'CAA'}, 'ResourceRecordSets': {'Type': {'CAA'}}}
Lists the resource record sets in a specified hosted zone.
ListResourceRecordSets returns up to 100 resource record sets at a time in ASCII order, beginning at a position specified by the name and type elements. The action sorts results first by DNS name with the labels reversed, for example:
com.example.www.
Note the trailing dot, which can change the sort order in some circumstances.
When multiple records have the same DNS name, the action sorts results by the record type.
You can use the name and type elements to adjust the beginning position of the list of resource record sets returned:
If you do not specify Name or Type
The results begin with the first resource record set that the hosted zone contains.
If you specify Name but not Type
The results begin with the first resource record set in the list whose name is greater than or equal to Name.
If you specify Type but not Name
Amazon Route 53 returns the InvalidInput error.
If you specify both Name and Type
The results begin with the first resource record set in the list whose name is greater than or equal to Name, and whose type is greater than or equal to Type.
This action returns the most current version of the records. This includes records that are PENDING, and that are not yet available on all Amazon Route 53 DNS servers.
To ensure that you get an accurate listing of the resource record sets for a hosted zone at a point in time, do not submit a ChangeResourceRecordSets request while you're paging through the results of a ListResourceRecordSets request. If you do, some pages may display results without the latest changes while other pages display results with the latest changes.

Response Structure
(dict) --
A complex type that contains list information for the resource record set.
ResourceRecordSets (list) --
Information about multiple resource record sets.
(dict) --
Information about the resource record set to create or delete.
Name (string) --
The name of the domain you want to perform the action on.
Enter a fully qualified domain name, for example, www.example.com. You can optionally include a trailing dot. If you omit the trailing dot, Amazon Route 53 still assumes that the domain name that you specify is fully qualified. This means that Amazon Route 53 treats www.example.com (without a trailing dot) and www.example.com. (with a trailing dot) as identical.
For information about how to specify characters other than a-z, 0-9, and - (hyphen) and how to specify internationalized domain names, see DNS Domain Name Format in the Amazon Route 53 Developer Guide.
You can use the asterisk (*) wildcard to replace the leftmost label in a domain name, for example, *.example.com. Note the following:
The * must replace the entire label. For example, you can't specify *prod.example.com or prod*.example.com.
The * can't replace any of the middle labels, for example, marketing.*.example.com.
If you include * in any position other than the leftmost label in a domain name, DNS treats it as an * character (ASCII 42), not as a wildcard.
You can use the * wildcard as the leftmost label in a domain name, for example, *.example.com. You can't use an * for one of the middle labels, for example, marketing.*.example.com. In addition, the * must replace the entire label; for example, you can't specify prod*.example.com.
Type (string) --
The DNS record type. For information about different record types and how data is encoded for them, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide.
Valid values for basic resource record sets: A | AAAA | CAA | CNAME | MX | NAPTR | NS | PTR | SOA | SPF | SRV | TXT
Values for weighted, latency, geolocation, and failover resource record sets: A | AAAA | CAA | CNAME | MX | NAPTR | PTR | SPF | SRV | TXT. When creating a group of weighted, latency, geolocation, or failover resource record sets, specify the same value for all of the resource record sets in the group.
Valid values for multivalue answer resource record sets: A | AAAA | MX | NAPTR | PTR | SPF | SRV | TXT
Values for alias resource record sets:
CloudFront distributions: A If IPv6 is enabled for the distribution, create two resource record sets to route traffic to your distribution, one with a value of A and one with a value of AAAA.
AWS Elastic Beanstalk environment that has a regionalized subdomain: A
ELB load balancers: A | AAAA
Amazon S3 buckets: A
Another resource record set in this hosted zone: Specify the type of the resource record set that you're creating the alias for. All values are supported except NS and SOA.
SetIdentifier (string) --
Weighted, Latency, Geo, and Failover resource record sets only: An identifier that differentiates among multiple resource record sets that have the same combination of DNS name and type. The value of SetIdentifier must be unique for each resource record set that has the same combination of DNS name and type. Omit SetIdentifier for any other types of record sets.
Weight (integer) --
Weighted resource record sets only: Among resource record sets that have the same combination of DNS name and type, a value that determines the proportion of DNS queries that Amazon Route 53 responds to using the current resource record set. Amazon Route 53 calculates the sum of the weights for the resource record sets that have the same combination of DNS name and type. Amazon Route 53 then responds to queries based on the ratio of a resource's weight to the total. Note the following:
You must specify a value for the Weight element for every weighted resource record set.
You can only specify one ResourceRecord per weighted resource record set.
You can't create latency, failover, or geolocation resource record sets that have the same values for the Name and Type elements as weighted resource record sets.
You can create a maximum of 100 weighted resource record sets that have the same values for the Name and Type elements.
For weighted (but not weighted alias) resource record sets, if you set Weight to 0 for a resource record set, Amazon Route 53 never responds to queries with the applicable value for that resource record set. However, if you set Weight to 0 for all resource record sets that have the same combination of DNS name and type, traffic is routed to all resources with equal probability. The effect of setting Weight to 0 is different when you associate health checks with weighted resource record sets. For more information, see Options for Configuring Amazon Route 53 Active-Active and Active-Passive Failover in the Amazon Route 53 Developer Guide.
Region (string) --
Latency-based resource record sets only: The Amazon EC2 Region where you created the resource that this resource record set refers to. The resource typically is an AWS resource, such as an EC2 instance or an ELB load balancer, and is referred to by an IP address or a DNS domain name, depending on the record type.
When Amazon Route 53 receives a DNS query for a domain name and type for which you have created latency resource record sets, Amazon Route 53 selects the latency resource record set that has the lowest latency between the end user and the associated Amazon EC2 Region. Amazon Route 53 then returns the value that is associated with the selected resource record set.
Note the following:
You can only specify one ResourceRecord per latency resource record set.
You can only create one latency resource record set for each Amazon EC2 Region.
You aren't required to create latency resource record sets for all Amazon EC2 Regions. Amazon Route 53 will choose the region with the best latency from among the regions that you create latency resource record sets for.
You can't create non-latency resource record sets that have the same values for the Name and Type elements as latency resource record sets.
GeoLocation (dict) --
Geo location resource record sets only: A complex type that lets you control how Amazon Route 53 responds to DNS queries based on the geographic origin of the query. For example, if you want all queries from Africa to be routed to a web server with an IP address of 192.0.2.111, create a resource record set with a Type of A and a ContinentCode of AF.
If you create separate resource record sets for overlapping geographic regions (for example, one resource record set for a continent and one for a country on the same continent), priority goes to the smallest geographic region. This allows you to route most queries for a continent to one resource and to route queries for a country on that continent to a different resource.
You can't create two geolocation resource record sets that specify the same geographic location.
The value * in the CountryCode element matches all geographic locations that aren't specified in other geolocation resource record sets that have the same values for the Name and Type elements.
You can't create non-geolocation resource record sets that have the same values for the Name and Type elements as geolocation resource record sets.
ContinentCode (string) --
The two-letter code for the continent.
Valid values: AF | AN | AS | EU | OC | NA | SA
Constraint: Specifying ContinentCode with either CountryCode or SubdivisionCode returns an InvalidInput error.
CountryCode (string) --
The two-letter code for the country.
SubdivisionCode (string) --
The code for the subdivision, for example, a state in the United States or a province in Canada.
Failover (string) --
Failover resource record sets only: To configure failover, you add the Failover element to two resource record sets. For one resource record set, you specify PRIMARY as the value for Failover; for the other resource record set, you specify SECONDARY. In addition, you include the HealthCheckId element and specify the health check that you want Amazon Route 53 to perform for each resource record set.
Except where noted, the following failover behaviors assume that you have included the HealthCheckId element in both resource record sets:
When the primary resource record set is healthy, Amazon Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the secondary resource record set.
When the primary resource record set is unhealthy and the secondary resource record set is healthy, Amazon Route 53 responds to DNS queries with the applicable value from the secondary resource record set.
When the secondary resource record set is unhealthy, Amazon Route 53 responds to DNS queries with the applicable value from the primary resource record set regardless of the health of the primary resource record set.
If you omit the HealthCheckId element for the secondary resource record set, and if the primary resource record set is unhealthy, Amazon Route 53 always responds to DNS queries with the applicable value from the secondary resource record set. This is true regardless of the health of the associated endpoint.
You can't create non-failover resource record sets that have the same values for the Name and Type elements as failover resource record sets.
For failover alias resource record sets, you must also include the EvaluateTargetHealth element and set the value to true.
For more information about configuring failover for Amazon Route 53, see the following topics in the Amazon Route 53 Developer Guide:
MultiValueAnswer (boolean) --
Multivalue answer resource record sets only: To route traffic approximately randomly to multiple resources, such as web servers, create one multivalue answer record for each resource and specify true for MultiValueAnswer. Note the following:
If you associate a health check with a multivalue answer resource record set, Amazon Route 53 responds to DNS queries with the corresponding IP address only when the health check is healthy.
If you don't associate a health check with a multivalue answer record, Amazon Route 53 always considers the record to be healthy.
Amazon Route 53 responds to DNS queries with up to eight healthy records; if you have eight or fewer healthy records, Amazon Route 53 responds to all DNS queries with all the healthy records.
If you have more than eight healthy records, Amazon Route 53 responds to different DNS resolvers with different combinations of healthy records.
When all records are unhealthy, Amazon Route 53 responds to DNS queries with up to eight unhealthy records.
If a resource becomes unavailable after a resolver caches a response, client software typically tries another of the IP addresses in the response.
You can't create multivalue answer alias records.
TTL (integer) --
The resource record cache time to live (TTL), in seconds. Note the following:
If you're creating or updating an alias resource record set, omit TTL. Amazon Route 53 uses the value of TTL for the alias target.
If you're associating this resource record set with a health check (if you're adding a HealthCheckId element), we recommend that you specify a TTL of 60 seconds or less so clients respond quickly to changes in health status.
All of the resource record sets in a group of weighted resource record sets must have the same value for TTL.
If a group of weighted resource record sets includes one or more weighted alias resource record sets for which the alias target is an ELB load balancer, we recommend that you specify a TTL of 60 seconds for all of the non-alias weighted resource record sets that have the same name and type. Values other than 60 seconds (the TTL for load balancers) will change the effect of the values that you specify for Weight.
ResourceRecords (list) --
Information about the resource records to act upon.
(dict) --
Information specific to the resource record.
Value (string) --
The current or new DNS record value, not to exceed 4,000 characters. In the case of a DELETE action, if the current value does not match the actual value, an error is returned. For descriptions about how to format Value for different record types, see Supported DNS Resource Record Types in the Amazon Route 53 Developer Guide.
You can specify more than one value for all record types except CNAME and SOA.
AliasTarget (dict) --
Alias resource record sets only: Information about the CloudFront distribution, AWS Elastic Beanstalk environment, ELB load balancer, Amazon S3 bucket, or Amazon Route 53 resource record set to which you're redirecting queries. The AWS Elastic Beanstalk environment must have a regionalized subdomain.
If you're creating resource records sets for a private hosted zone, note the following:
You can't create alias resource record sets for CloudFront distributions in a private hosted zone.
Creating geolocation alias resource record sets or latency alias resource record sets in a private hosted zone is unsupported.
For information about creating failover resource record sets in a private hosted zone, see Configuring Failover in a Private Hosted Zone in the Amazon Route 53 Developer Guide.
HostedZoneId (string) --
Alias resource records sets only: The value used depends on where you want to route traffic:
CloudFront distribution
Specify Z2FDTNDATAQYW2.
Specify the hosted zone ID for the region in which you created the environment. The environment must have a regionalized subdomain. For a list of regions and the corresponding hosted zone IDs, see AWS Elastic Beanstalk in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference.
ELB load balancer
Specify the value of the hosted zone ID for the load balancer. Use the following methods to get the hosted zone ID:
Elastic Load Balancing table in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference: Use the value in the "Amazon Route 53 Hosted Zone ID" column that corresponds with the region that you created your load balancer in.
AWS Management Console: Go to the Amazon EC2 page, click Load Balancers in the navigation pane, select the load balancer, and get the value of the Hosted zone field on the Description tab.
Elastic Load Balancing API: Use DescribeLoadBalancers to get the value of CanonicalHostedZoneNameId. For more information, see the applicable guide:
Classic Load Balancer: DescribeLoadBalancers
Application Load Balancer: DescribeLoadBalancers
AWS CLI: Use describe-load-balancers to get the value of CanonicalHostedZoneNameID.
An Amazon S3 bucket configured as a static website
Specify the hosted zone ID for the region that you created the bucket in. For more information about valid values, see the Amazon Simple Storage Service Website Endpoints table in the "AWS Regions and Endpoints" chapter of the Amazon Web Services General Reference.
Another Amazon Route 53 resource record set in your hosted zone
Specify the hosted zone ID of your hosted zone. (An alias resource record set can't reference a resource record set in a different hosted zone.)
DNSName (string) --
Alias resource record sets only: The value that you specify depends on where you want to route queries:
CloudFront distribution
Specify the domain name that CloudFront assigned when you created your distribution.
Your CloudFront distribution must include an alternate domain name that matches the name of the resource record set. For example, if the name of the resource record set is acme.example.com, your CloudFront distribution must include acme.example.com as one of the alternate domain names. For more information, see Using Alternate Domain Names (CNAMEs) in the Amazon CloudFront Developer Guide.
Elastic Beanstalk environment
Specify the CNAME attribute for the environment. (The environment must have a regionalized domain name.) You can use the following methods to get the value of the CNAME attribute:
AWS Management Console: For information about how to get the value by using the console, see Using Custom Domains with AWS Elastic Beanstalk in the AWS Elastic Beanstalk Developer Guide.
Elastic Beanstalk API: Use the DescribeEnvironments action to get the value of the CNAME attribute. For more information, see DescribeEnvironments in the AWS Elastic Beanstalk API Reference.
AWS CLI: Use the describe-environments command to get the value of the CNAME attribute. For more information, see describe-environments in the AWS Command Line Interface Reference.
ELB load balancer
Specify the DNS name that is associated with the load balancer. Get the DNS name by using the AWS Management Console, the ELB API, or the AWS CLI.
AWS Management Console: Go to the EC2 page, choose Load Balancers in the navigation pane, choose the load balancer, choose the Description tab, and get the value of the DNS name field. (If you're routing traffic to a Classic Load Balancer, get the value that begins with dualstack.)
Elastic Load Balancing API: Use DescribeLoadBalancers to get the value of DNSName. For more information, see the applicable guide:
Classic Load Balancer: DescribeLoadBalancers
Application Load Balancer: DescribeLoadBalancers
AWS CLI: Use describe-load-balancers to get the value of DNSName.
Amazon S3 bucket that is configured as a static website
Specify the domain name of the Amazon S3 website endpoint in which you created the bucket, for example, s3-website-us-east-2.amazonaws.com. For more information about valid values, see the table Amazon Simple Storage Service (S3) Website Endpoints in the Amazon Web Services General Reference. For more information about using S3 buckets for websites, see Getting Started with Amazon Route 53 in the Amazon Route 53 Developer Guide.
Another Amazon Route 53 resource record set
Specify the value of the Name element for a resource record set in the current hosted zone.
EvaluateTargetHealth (boolean) --
Applies only to alias, failover alias, geolocation alias, latency alias, and weighted alias resource record sets: When EvaluateTargetHealth is true, an alias resource record set inherits the health of the referenced AWS resource, such as an ELB load balancer, or the referenced resource record set.
Note the following:
You can't set EvaluateTargetHealth to true when the alias target is a CloudFront distribution.
If the AWS resource that you specify in AliasTarget is a resource record set or a group of resource record sets (for example, a group of weighted resource record sets), but it is not another alias resource record set, we recommend that you associate a health check with all of the resource record sets in the alias target. For more information, see What Happens When You Omit Health Checks? in the Amazon Route 53 Developer Guide.
If you specify an Elastic Beanstalk environment in HostedZoneId and DNSName, and if the environment contains an ELB load balancer, Elastic Load Balancing routes queries only to the healthy Amazon EC2 instances that are registered with the load balancer. (An environment automatically contains an ELB load balancer if it includes more than one EC2 instance.) If you set EvaluateTargetHealth to true and either no EC2 instances are healthy or the load balancer itself is unhealthy, Amazon Route 53 routes queries to other available resources that are healthy, if any. If the environment contains a single EC2 instance, there are no special requirements.
If you specify an ELB load balancer in AliasTarget ``, ELB routes queries only to the healthy EC2 instances that are registered with the load balancer. If no EC2 instances are healthy or if the load balancer itself is unhealthy, and if ``EvaluateTargetHealth is true for the corresponding alias resource record set, Amazon Route 53 routes queries to other resources. When you create a load balancer, you configure settings for ELB health checks; they're not Amazon Route 53 health checks, but they perform a similar function. Do not create Amazon Route 53 health checks for the EC2 instances that you register with an ELB load balancer. For more information, see How Health Checks Work in More Complex Amazon Route 53 Configurations in the Amazon Route 53 Developer Guide.
We recommend that you set EvaluateTargetHealth to true only when you have enough idle capacity to handle the failure of one or more endpoints.
For more information and examples, see Amazon Route 53 Health Checks and DNS Failover in the Amazon Route 53 Developer Guide.
HealthCheckId (string) --
If you want Amazon Route 53 to return this resource record set in response to a DNS query only when a health check is passing, include the HealthCheckId element and specify the ID of the applicable health check.
Amazon Route 53 determines whether a resource record set is healthy based on one of the following:
By periodically sending a request to the endpoint that is specified in the health check
By aggregating the status of a specified group of health checks (calculated health checks)
By determining the current state of a CloudWatch alarm (CloudWatch metric health checks)
For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy.
The HealthCheckId element is only useful when Amazon Route 53 is choosing between two or more resource record sets to respond to a DNS query, and you want Amazon Route 53 to base the choice in part on the status of a health check. Configuring health checks only makes sense in the following configurations:
You're checking the health of the resource record sets in a group of weighted, latency, geolocation, or failover resource record sets, and you specify health check IDs for all of the resource record sets. If the health check for one resource record set specifies an endpoint that is not healthy, Amazon Route 53 stops responding to queries using the value for that resource record set.
You set EvaluateTargetHealth to true for the resource record sets in a group of alias, weighted alias, latency alias, geolocation alias, or failover alias resource record sets, and you specify health check IDs for all of the resource record sets that are referenced by the alias resource record sets.
For geolocation resource record sets, if an endpoint is unhealthy, Amazon Route 53 looks for a resource record set for the larger, associated geographic region. For example, suppose you have resource record sets for a state in the United States, for the United States, for North America, and for all locations. If the endpoint for the state resource record set is unhealthy, Amazon Route 53 checks the resource record sets for the United States, for North America, and for all locations (a resource record set for which the value of CountryCode is *), in that order, until it finds a resource record set for which the endpoint is healthy.
If your health checks specify the endpoint only by domain name, we recommend that you create a separate health check for each endpoint. For example, create a health check for each HTTP server that is serving content for www.example.com. For the value of FullyQualifiedDomainName, specify the domain name of the server (such as us-east-2-www.example.com), not the name of the resource record sets (example.com).
For more information, see the following topics in the Amazon Route 53 Developer Guide:
TrafficPolicyInstanceId (string) --
When you create a traffic policy instance, Amazon Route 53 automatically creates a resource record set. TrafficPolicyInstanceId is the ID of the traffic policy instance that Amazon Route 53 created this resource record set for.
IsTruncated (boolean) --
A flag that indicates whether more resource record sets remain to be listed. If your results were truncated, you can make a follow-up pagination request by using the NextRecordName element.
NextRecordName (string) --

Response Structure
(dict) --
A complex type that contains the response to a TestDNSAnswer request.
Nameserver (string) --
The Amazon Route 53 name server used to respond to the request.
RecordName (string) --
The name of the resource record set that you submitted a request for.
RecordType (string) --
The type of the resource record set that you submitted a request for.
RecordData (list) --
A list that contains values that Amazon Route 53 returned for this resource record set.
(string) --
A value that Amazon Route 53 returned for this resource record set. A RecordDataEntry element is one of the following:
For non-alias resource record sets, a RecordDataEntry element contains one value in the resource record set. If the resource record set contains multiple values, the response includes one RecordDataEntry element for each value.
For multiple resource record sets that have the same name and type, which includes weighted, latency, geolocation, and failover, a RecordDataEntry element contains the value from the appropriate resource record set based on the request.
For alias resource record sets that refer to AWS resources other than another resource record set, the RecordDataEntry element contains an IP address or a domain name for the AWS resource, depending on the type of resource.
For alias resource record sets that refer to other resource record sets, a RecordDataEntry element contains one value from the referenced resource record set. If the referenced resource record set contains multiple values, the response includes one RecordDataEntry element for each value.
ResponseCode (string) --
A code that indicates whether the request is valid or not. The most common response code is NOERROR, meaning that the request is valid. If the response is not valid, Amazon Route 53 returns a response code that describes the error. For a list of possible response codes, see DNS RCODES on the IANA website.
Protocol (string) --
The protocol that Amazon Route 53 used to respond to the request, either UDP or TCP.
{'TrafficPolicy': {'Type': {'CAA'}}}

A complex type that contains settings for the specified traffic policy.
Id (string) --
The ID that Amazon Route 53 assigned to a traffic policy when you created it.
Version (integer) --
The version number that Amazon Route 53 assigns to a traffic policy. For a new traffic policy, the value of Version is always 1.
Name (string) --
The name that you specified when you created the traffic policy.
Type (string) --
The DNS type of the resource record sets that Amazon Route 53 creates when you use a traffic policy to create a traffic policy instance.
Document (string) --
The definition of a traffic policy in JSON format. You specify the JSON document to use for a new traffic policy in the CreateTrafficPolicy request. For more information about the JSON format, see Traffic Policy Document Format.
Comment (string) --
The comment that you specify in the CreateTrafficPolicy request, if any.
{'TrafficPolicyInstance': {'TrafficPolicyType': {'CAA'}}}
Updates the resource record sets in a specified hosted zone that were created based on the settings in a specified traffic policy version.
When you update a traffic policy instance, Amazon Route 53 continues to respond to DNS queries for the root resource record set name (such as example.com) while it replaces one group of resource record sets with another. Amazon Route 53 performs the following operations:
Amazon Route 53 creates a new group of resource record sets based on the specified traffic policy. This is true regardless of how significant the differences are between the existing resource record sets and the new resource record sets.
When all of the new resource record sets have been created, Amazon Route 53 starts to respond to DNS queries for the root resource record set name (such as example.com) by using the new resource record sets.
Amazon Route 53 deletes the old group of resource record sets that are associated with the root resource record set name.
