2020/05/05 - Amazon Elastic Compute Cloud - 4 updated api methods
Changes With this release, you can call ModifySubnetAttribute with two new parameters: MapCustomerOwnedIpOnLaunch and CustomerOwnedIpv4Pool, to map a customerOwnedIpv4Pool to a subnet. You will also see these two new fields in the DescribeSubnets response. If your subnet has a customerOwnedIpv4Pool mapped, your network interface will get an auto assigned customerOwnedIpv4 address when placed onto an instance.
{'Subnet': {'CustomerOwnedIpv4Pool': 'string',
'MapCustomerOwnedIpOnLaunch': 'boolean'}}
Creates a default subnet with a size /20 IPv4 CIDR block in the specified Availability Zone in your default VPC. You can have only one default subnet per Availability Zone. For more information, see Creating a Default Subnet in the Amazon Virtual Private Cloud User Guide .

{'Subnet': {'CustomerOwnedIpv4Pool': 'string',
'MapCustomerOwnedIpOnLaunch': 'boolean'}}
Creates a subnet in an existing VPC.
When you create each subnet, you provide the VPC ID and IPv4 CIDR block for the subnet. After you create a subnet, you can't change its CIDR block. The size of the subnet's IPv4 CIDR block can be the same as a VPC's IPv4 CIDR block, or a subset of a VPC's IPv4 CIDR block. If you create more than one subnet in a VPC, the subnets' CIDR blocks must not overlap. The smallest IPv4 subnet (and VPC) you can create uses a /28 netmask (16 IPv4 addresses), and the largest uses a /16 netmask (65,536 IPv4 addresses).
If you've associated an IPv6 CIDR block with your VPC, you can create a subnet with an IPv6 CIDR block that uses a /64 prefix length.
Warning
AWS reserves both the first four and the last IPv4 address in each subnet's CIDR block. They're not available for use.
If you add more than one subnet to a VPC, they're set up in a star topology with a logical router in the middle.
If you launch an instance in a VPC using an Amazon EBS-backed AMI, the IP address doesn't change if you stop and restart the instance (unlike a similar instance launched outside a VPC, which gets a new IP address when restarted). It's therefore possible to have a subnet with no running instances (they're all stopped), but no remaining IP addresses available.
For more information about subnets, see Your VPC and Subnets in the Amazon Virtual Private Cloud User Guide .

string
The Availability Zone or Local Zone for the subnet.
Default: AWS selects one for you. If you create more than one subnet in your VPC, we do not necessarily select a different zone for each subnet.
To create a subnet in a Local Zone, set this value to the Local Zone ID, for example us-west-2-lax-1a . For information about the Regions that support Local Zones, see Available Regions in the Amazon Elastic Compute Cloud User Guide .
To create a subnet in an Outpost, set this value to the Availability Zone for the Outpost and specify the Outpost ARN.
