-- Releases the specified Elastic IP address.
--
-- After releasing an Elastic IP address, it is released to the IP address
-- pool and might be unavailable to you. 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.
--
-- [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.
--
-- [Nondefault VPC] You must use DisassociateAddress to disassociate the
-- Elastic IP address before you try to release it. Otherwise, Amazon EC2
-- returns an error ('InvalidIPAddress.InUse').
