What [8] shows is that nsa.gov resolves to 65.196.127.226. 65.196.127.226 is part of the range 65.192.0.0/11 assigned to AS (autonomous system) 701, which is "UUnet Technologies, Inc". From Wikipedia, "Today, UUNET is an internal brand of Verizon Business". Both 65.196.127.226 (the server that hosts nsa.gov) and 65.222.202.53 fall in the same /11 block (i.e. a block of 2,097,152 addresses) assigned to UUnet / Verizon Business. However, that is a huge block of IP addresses, and numerous other servers are also hosted by Verizon Business on that block - http://route.robtex.com/65.192.0.0-11.html http://route.robtex.com/65.192.0.0-11.html will give you a list. It is entirely possible that the Verizon Business is providing services to some US government agency to run 65.222.202.53, but the fact that NSA also uses Verizon Business to host its website is hardly conclusive proof of anything.
