We pick b.root-servers.net, one of the 13 root servers (1), and ask it about j.psex.com and learn that com is delegated to 13 name servers (2), so we ask a.gtld-servers.net where we learn that psex.com is delegated to two name servers, including ns2.rookdns.com (3), so we ask that one and get the following answer:
A third of them point only to the IP number 141.8.224.25 (example: xba.com, svetsa.se and apunkabolywood.com ). Worth noting is that three quarter of the host names that point only to the IP number 141.8.224.25 use name server group 1.
