-- Associates an Elastic IP address with an instance or a network interface.
--
-- An Elastic IP address is for use in either the EC2-Classic platform or in a VPC. For more information, see <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html Elastic IP Addresses> in the /Amazon Elastic Compute Cloud User Guide/.
--
-- [EC2-Classic, VPC in an EC2-VPC-only account] If the Elastic IP address is already associated with a different instance, it is disassociated from that instance and associated with the specified instance.
--
-- [VPC in an EC2-Classic account] If you don\'t specify a private IP address, the Elastic IP address is associated with the primary IP address. If the Elastic IP address is already associated with a different instance or a network interface, you get an error unless you allow reassociation.
--
-- This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn\'t return an error.

-- | [EC2-VPC] For a VPC in an EC2-Classic account, specify true to allow an Elastic IP address that is already associated with an instance or network interface to be reassociated with the specified instance or network interface. Otherwise, the operation fails. In a VPC in an EC2-VPC-only account, reassociation is automatic, therefore you can specify false to ensure the operation fails if the Elastic IP address is already associated with another resource.
