It really, really bugs me when people who have websites don’t bother to setup their DNS servers such that the website resolves without a “www.” prepended. Case in point, CU-Denver (No WWW) and CU-Denver.
[Later] On further review, it would appear that DNS for cudenver.edu is almost correct — it’s just that the first record (of 4) points to a 192.168.* address instead of the external IP that they should use. Still, I’ve seen other sites have similar problems and it’s just lame…imnsho, of course.
