Log surfing

So, I'm wandering through my httpd logs, and I notice that some folks have really funny machine names. What's most interesting, though, is that a lot of the military domains are goofily named. For instance:

squid1.tacom.army.mil
jaguar.andrews.af.mil
centurion.warren.af.mil
viper.usafa.af.mil
B-Kahuna.hickam.af.mil

Alas, the vast majority of military domains, as most com and edu ones as well, are dull and cryptic. wrtc53254-139.westriv.com, anyone?
