We pick h.root-servers.net, one of the 13 root servers (1), and ask it about i-dns.kr and learn that kr is delegated to six name servers (2), so we ask g.dns.kr where we learn that i-dns.kr is delegated to two name servers, including ns3.comn.com (3), so we ask that one and get the following answer:
All of the more than a thousands domains that use the primary name server ns1.comn.com use name server group 1 (example: teletutto.com, smida.com and mycontents.net ). Worth noting is that all of the domains that use name server group 1 use the primary name server ns1.comn.com.
The two name servers ns1 and ns2.comn.com together
There are more than a thousands domains that use name server group 1.
