Funny, I wonder why you didn't get the original NANOG post - the URL to
which I copied in my last post.

Actually, I did a brief perusal of the archives on www.nanog.org and didn't
find the final version.  Does anyone have a copy I can post on the web site?

Thanx, but there is a minor error in that one too. :)  Don't use the
192.0.0.0/8 line.  (Not that it should hurt anything, but don't use it
anyway.)  I'll be putting up a better one in a little while.

If you go to the URL I copied in my last post and look at the threads
surrounding it, Sean's logic is partially exposed in posts to this very
list - as well as other peoples' reactions to his logic.  (Please note that
I am in no way claiming to know why Sean did something, just pointing out
that he posted some reasons to NANOG that might clarify his reasoning.)

Heh.  Those damned robots. :)
