Way back when the Interwebz were just a twinkle in Mr. Berners-Lee eye, high-speed networks were 56K (when you could use the phone line), and domains without exclamation marks in them [1] were all shiny and new, I was supervising IT at a particular municipality. Nobody quite knew how this DNS thing was supposed to be arranged, but like any good Yellow Pages it should be arranged geographically. So I filled out a (paper) form and (paper) mailed it to the registrar, and got us a (free) (for life) domain--ci.<9letrcity>.<st>.us. Just checked, they're still using it. No telling how many times I've been anonymously cursed.

Edit: Think I got us a Class C too, although we had no way to route it.
