This stuff is hard to get right - I implemented this on top of pydns, and it was a lot of work to get (what I think is) correct, for not very much gain. The idea of either suppressing DNS lookups for all-numeric addresses, or some sort of extended API for suppressing DNS lookups might be better, but really, isn't this the job of the stub resolver? This is part of the resolver API, via the AI_NUMERIC flags. I am just trying to expose that API to the top level of python.
