Wow. Just took a look at
FixedOrbit.com's statistics page, and saw the top 10 networks list, by number of IP addresses controlled. The results are somewhat interesting. Tops on the list is DISA CONUS, or (effectively) the US military. Makes sense. The next four are the Tier 1s (owners of the backbone, essentially): Level 3, AT&T WorldNet, Cogent, and UUNET. Again, makes sense.
Coming at number 6?
Oh, go ahead, guess.
Take a stab. A shot in the dark.
Got one?
Think you've got it right?
THE UNIVERSITY OF WISCONSIN - MADISON.
WTF, MATES?
What on earth is the UW doing with eighteen million IP addresses? That's more than one complete class-A, for crying out loud, and there are only 64 of those to go around!
I'm completely boggled.
For the record, the next four are: Hewlett-Packard, Merit Network (I have no idea who this is), AT&T Global Network, and SBC Internet.
