Use your BYOIP address range in Amazon EC2

You can view and use the IPv4 and IPv6 address ranges that you've provisioned in your account. For more information, see Onboard your address range for use in Amazon EC2.

IPv4 address ranges

You can create an Elastic IP address from your IPv4 address pool and use it with your AWS resources, such as EC2 instances, NAT gateways, and Network Load Balancers.

To view information about the IPv4 address pools that you've provisioned in your account, use the following describe-public-ipv4-pools command.

aws ec2 describe-public-ipv4-pools --region us-east-1

To create an Elastic IP address from your IPv4 address pool, use the allocate-address command. You can use the --public-ipv4-pool option to specify the ID of the address pool returned by describe-byoip-cidrs. Or you can use the --address option to specify an address from the address range that you provisioned.

IPv6 address ranges

To view information about the IPv6 address pools that you've provisioned in your account, use the following describe-ipv6-pools command.

aws ec2 describe-ipv6-pools --region us-east-1

To create a VPC and specify an IPv6 CIDR from your IPv6 address pool, use the following create-vpc command. To let Amazon choose the IPv6 CIDR from your IPv6 address pool, omit the --ipv6-cidr-block option.

aws ec2 create-vpc --cidr-block 10.0.0.0/16 --ipv6-cidr-block ipv6-cidr --ipv6-pool pool-id --region us-east-1

To associate an IPv6 CIDR block from your IPv6 address pool with a VPC, use the following associate-vpc-cidr-block command. To let Amazon choose the IPv6 CIDR from your IPv6 address pool, omit the --ipv6-cidr-block option.

aws ec2 associate-vpc-cidr-block --vpc-id vpc-123456789abc123ab --ipv6-cidr-block ipv6-cidr --ipv6-pool pool-id --region us-east-1

To view your VPCs and the associated IPv6 address pool information, use the describe-vpcs command. To view information about associated IPv6 CIDR blocks from a specific IPv6 address pool, use the following get-associated-ipv6-pool-cidrs command.

aws ec2 get-associated-ipv6-pool-cidrs --pool-id pool-id --region us-east-1

If you disassociate the IPv6 CIDR block from your VPC, it's released back into your IPv6 address pool.
