Releases the specified Elastic IP address.
[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.
[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 AWS account.
After you release an Elastic IP address, you might be able to recover it. For more information, see AllocateAddress.
