POST /#Action=ReleaseAddress
Releases the specified Elastic IP address.
[EC2-Classic, default VPC] Releasing an Elastic IP address automatically disassociates it from any instance that it's associated with. To disassociate an Elastic IP address without releasing it, use DisassociateAddress.
We are retiring EC2-Classic. We recommend that you migrate from EC2-Classic to a VPC. For more information, see Migrate from EC2-Classic to a VPC in the Amazon Elastic Compute Cloud User Guide.
[Nondefault VPC] You must use DisassociateAddress to disassociate the Elastic IP address before you can release it. Otherwise, Amazon EC2 returns an error (InvalidIPAddress.InUse).
After releasing an Elastic IP address, it is released to the IP address pool. Be sure to update your DNS records and any servers or devices that communicate with the address. If you attempt to release an Elastic IP address that you already released, you'll get an AuthFailure error if the address is already allocated to another Amazon Web Services account.
[EC2-VPC] After you release an Elastic IP address for use in a VPC, you might be able to recover it. For more information, see AllocateAddress.
For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.
