How do I move my BYOIP CIDR from one account to another account using IPAM?

Short description

You have provisioned a BYOIP CIDR to an account without using IPAM. Now you want to manage the BYOIP CIDR using IPAM.

Resolution

Note: If you're the IPAM owner, complete steps 1-4. Complete step 5, if you're the BYOIP CIDR owner.

Follow the steps given below to add BYOIP to another account in the Organization:

1. Designate an IPAM admin account in the AWS Organization other than the root account. For more information, see Integrate IPAM with accounts in an AWS Organization.
2. Use this IPAM Administrator's account to create an IPAM. For more information, see Create an IPAM.
3. Create an IPv4 top-level pool. Make sure you meet the following requirements when creating the public pool:

• The pool is a top-level pool.
• The pool is using IPv4.
• The pool must have a locale equal to the region the BYOIP CIDR is in.
• The AWS service for the pool is set to Amazon Elastic Compute Cloud (Amazon EC2).
• The pool's Public IP source is set to BYOIP.

5. Share the IPAM pool using AWS Resource Access Manager (RAM).
6. Transfer BYOIP to IPAM.

Now, other accounts in the AWS Organization can use the IP addresses from the BYOIP pool.
