Reverse DNS does not give you all the hostnames that can point to a particular IP address though.

Other than brute forcing, I don't think anything does — that's the beauty and the curse of a proper federated system :)

In fact, it might not even give you any names that point to an IP address, since it might be out of sync with the forward system, especially if the records are built by hand.
