aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html"> Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide .

[EC2-Classic, default VPC] If the Elastic IP address is already associated with a different instance, it is disassociated from that instance and associated with the specified instance.

[EC2-VPC] 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.

@param associateAddressRequest Container for the necessary parametersto execute the AssociateAddress service method on AmazonEC2. @return The response from the AssociateAddress service method, asreturned by AmazonEC2. @throws AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available. @throws AmazonServiceException If an error response is returned by AmazonEC2 indicating either a problem with the data in the request, or a server side issue.
