It's worth checking out Matt Zook's work at UC Berkeley.

Note that he mostly uses the various addresses posted in
the various DNS fields. For example, the top entry for
domain name holding ends up being "Namezero", which is
a free DNS service--despite the fact that they serve
addresses from all over the world.
