We pick f.root-servers.net, one of the 13 root servers (1), and ask it about movies2k.com and learn that com is delegated to 13 name servers (2), so we ask k.gtld-servers.net where we learn that movies2k.com is delegated to four name servers, including ns.pop-hannover.de (3), so we ask that one and get the following answer:
Five of them use the three name servers dns1, dns2 and dns3.piratenpartei.de together, hereafter referred to as "name server group 1".
The IP number 178.15.51.36 only
Five of the 13 host names that point only to the IP number 178.15.51.36 use name server group 1. Worth noting is that all of the domains that use name server group 1 point only to the IP number 178.15.51.36.
The three name servers dns1, dns2 and dns3.piratenpartei.de together
All of the four domains that use name server group 1 point only to the IP number 178.15.51.36. Worth noting is that four of the host names that point only to the IP number 178.15.51.36 use name server group 1.
