We pick d.root-servers.net, one of the 13 root servers (1), and ask it about tt.dk and learn that dk is delegated to six name servers (2), so we ask s.nic.dk where we learn that tt.dk is delegated to three name servers, including ns2.ascio.net (3), so we ask that one and get the following answer:
Eleven percent of them use the two name servers ns1 and ns2.ascio.net together (but not ns3.ascio.net ), hereafter referred to as "name server group 2", (example: nge.dk, logistikforum.dk and dinaudi.com ). Worth noting is that two thirds of the domains that use name server group 2 point only to the IP number 212.53.95.124.
The three name servers ns1, ns2 and ns3.ascio.net together
There are several thousand of domains that use name server group 1.
