We pick f.root-servers.net, one of the 13 root servers (1), and ask it about ww.sexphoto.com and learn that com is delegated to 13 name servers (2), so we ask j.gtld-servers.net where we learn that sexphoto.com is delegated to two name servers, including ns2.sedoparking.com (3), so we ask that one and get the following answer:
At least one of them point to the two IP numbers 82.98.86.164 and 82.98.86.165 together, hereafter referred to as "IP group 1", (example: enigma-cafe.ru ).
The IP number 82.98.86.165 only
Three quarter of the several thousand of host names that point to the IP number 82.98.86.165 only (but not 82.98.86.164 ) use name server group 1 (example: awht.com, www.hit-search.de and nonnen.at ). Worth noting is that ten percent of the domains that use name server group 1 point to the IP number 82.98.86.165 only (but not 82.98.86.164 ).
The two IP numbers 82.98.86.164 and 82.98.86.165 together
All of the more than a thousands host names that point to IP group 1 use name server group 1.
