I wrote a script to check a bunch of popular domains (or any domain) and see if they have a reverse DNS entry.

The summary is that every one (100%) of the domains I checked had reverse DNS.

paying for operating systems is for suckers. i never have. and no, my stone cold heart feels nothing for the poor starving microsoft execs.

there's a dilbert for that: http://www.perturb.org/display/462_Dilbert___Unix.html

Actually, this is what I was thinking about. You get an actual entry in ifconfig, and with a little routing it should be entirely transparent to all applications.

For any who missed it (as parent apparently did) the byplay is a reference to a Dilbert, I spotted it at http://www.perturb.org/display/entry/462/

I like these icons better, the nicest FF and TBird icons I've seen. Kudos to whomever did them!

Manga-style underage girl dolls that scat. 40USD only ;) Pictures and order formhere. Now you know and your view of Japanese people is ruined, harrrrr harrrr.

These are pirates you gormless idiot.

You are talking about petty thievery.

If you can't tell the difference, maybe you should just shut up and stop making a fool of yourself in public.
