An "IP socket" is the unique combination of an IP address and a port number. I don't see why you couldn't run those separate instances of your db servers on the same port but each with their own addresses as they would each have their own unique "IP socket". I don't think you would create any collisions or contentions beyond that of pure network congestion.
