We pick k.root-servers.net, one of the 13 root servers (1), and ask it about pornography-photo.com and learn that com is delegated to 13 name servers (2), so we ask j.gtld-servers.net where we learn that pornography-photo.com is delegated to two name servers, including ns2.virtualxs.com (3), so we ask that one and get the following answer:
About one in six of the more than two hundred host names that point only to the IP number 62.129.133.179 use name server group 1 (example: dvd-sex-movie.net and teen-sex-chat.net ). Worth noting is that nine percent of the domains that use name server group 1 point only to the IP number 62.129.133.179.
The two name servers ns1 and ns2.virtualxs.com together
There are more than hundred domains that use name server group 2.
More than one in eight of the more than hundred host names that point only to the IP number 62.129.133.177 use name server group 1 (example: defloration.com, video-buy.com and sexcontent.biz ). Worth noting is that three percent of the domains that use name server group 1 point only to the IP number 62.129.133.177.
