I'm posting this here, because the PG boards will still not allow me to log in. When checking the IP of a supernode in ARIN the other day, I found it listed as Cogent Communications. They are now listing themselves as Cogeco, but I have them incorporated into my IP blocker as Cogent Communications. Anyways, here is what I am able to display from ARIN:
Cogeco Cable Inc. CGOC (NET-24-141-0-0-1)
22.214.171.124 - 126.96.36.199
Cogeco Cable Solutions CGOC-HATO1-1 (NET-24-141-96-0-1)
188.8.131.52 - 184.108.40.206
I believe they are acting as a supernode.
