Unfortunantly it wasn't that easy. This version doesn't segfault with
bad input :) Also just noticed there is a bunch of stuff going on with
ifconfig in current. So I guess this can just be a conversation starter,
and perhaps whomever is doing the work can possibly put something like
this in.

I hate to assume, but I'm going to assume that if one wants to scan for
