I skipped down a few to the next group...
107.77.90.121 - Atlanta
12.53.217.90 - Fort Pierce, FLA or Houston, TX
127.0.0.1 - returned an error. Resolves as an IPv4 address.

Based on these, it appears pretty clear he's using an onion router.
I use one on occasion, and have it turned on now. If you look at the IP from my post as Carson in
this thread, it resolves to my current setting of choice, Dallas. I can choose from 200 different IPs in the US or abroad, and that's what he's likely doing.
