We pick l.root-servers.net, one of the 13 root servers (1), and ask it about wwww.tv and learn that tv is delegated to seven name servers (2), so we ask a5.nstld.com where we learn that wwww.tv is delegated to four name servers, including f4.nstld.com (3), so we ask that one and get the following answer:
The seven name servers a4, f4, g4, h4, j4, k4 and l4.nstld.com together
A third of the several thousand of domains that use the seven name servers a4, f4, g4, h4, j4, k4 and l4.nstld.com together, hereafter referred to as "name server group 2", point only to the IP number 69.58.181.114 (example: crq.tv, lbd.tv and sexstory.tv ).
The four name servers a4, f4, g4 and l4.nstld.com together
There are several thousand of domains that use name server group 1.
