Twisted[1] comes with a DNS server built-in. For non-authorative local DNS caches: twistd dns --recursive --cache For authorative servers, to serve a BIND-style zonefile: twistd dns --bindzone ZONEFILE But, of course, that's pretty boring. The fun stuff is when you have a Python source file as your zonefile! See: https://twistedmatrix.com/documents/current/names/howto/names.html https://twistedmatrix.com/documents/current/names/howto/name... twisted.names (that's the name of the DNS package) is simple enough to use for DNS serving (demonstrated above) and flexible enough to get it to do pretty much whatever you want.
