gethostbyname is a simple function with not much flexibility. (You
can't, for instance, look up a TXT record.) For anything more complex,
you want a proper DNS implementation.

There are a few Python DNS modules. It means adding another
dependency, but perhaps not as large as twisted. And of course, you
could always manually send UDP packets and listen for responses, but
that seems a little unnecessary :)
