Most DNS providers allow you to specify wildcard DNS . That means you have an entry something like "*.example.com" that maps to your IP address.

If you do this, then you do not have to modify DNS entries on the fly, you just need to add an internal mapping in your database (or whatever) saying that "user1.example.com maps to user1", etc.
