Using Shodan, we can find other nodes belonging to the same CDN by
searching for "FP6.1.1866.55", which is conveniently present in the
"Server" HTTP header.
Skimming through the results, it would appear most of the nodes are on
the Level 3 network. Picking one non-Level3 node at random
(192.67.191.173) and doing an rDNS lookup reveals the following:
173.191.67.192.in-addr.arpa. 3600 IN PTR
LEVEL3-CDN-192-67-191-173.de.kpn-eurorings.net.
There's your answer. "Level 3 CDN".
Kind Regards,
Filip Hruska

Former Level3 operates a CDN. Might be worth looking into.

You might ask Level3.
