I'm not sure what you mean by applying the algorithm to IP quads? If you give me the name "google.com", there is no algorithm I can apply which yields the IP address, correct? Because that IP address could be reassigned to a different name, right? The only way I can make the connection is to do a DNS lookup, which I thought is essentially just searching a database for "google.com" and returning me the corresponding IP address.
