I keep thinking that I wrote up a technique in the draft ID to 
use the 'TXT' record so we can easily identify the true host's 
identity...I'll have to dig out my copy.  (no pun intended)

Hop 9 seems to be a Qwest address, with origin AS 209, if the DNS and 
route-views are to be trusted.  We can probably infer that Qwest or a 
customer of theirs has one.

Anyone here from Qwest that can vouch for that box?
