Hmm, documentation about this function is kinda weird (http://docs.aws.amazon.com/AWSEC2/latest/APIReference/ApiReference-query-AllocateAddress.html). It says that the only valid value for `Domain` parameter is `vpc`, but the example on the page also uses `standard` as a value.

Can you please verify with a live installation that it also supports `standard` as a value and it works as expected?
