We pick j.root-servers.net, one of the 13 root servers (1), and ask it about c.sweetheart.cc and learn that cc is delegated to seven name servers (2), so we ask c5.nstld.com where we learn that sweetheart.cc is delegated to six name servers, including ns4.sweetheart.cc (3), so we ask that one and get the following answer:
Three of them use the two name servers ns1 and ns2.value-domain.com together, hereafter referred to as "name server group 1".
The IP number 125.29.39.37 only
Three of the 15 host names that point only to the IP number 125.29.39.37 use name server group 1.
The six name servers ns, ns2, ns3, ns4, ns5 and ns6.c.sweetheart.cc together
There are one domains that use the six name servers ns, ns2, ns3, ns4, ns5 and ns6.c.sweetheart.cc together, hereafter referred to as "name server group 2".
All of those use only the mail server mail.c.sweetheart.cc. Worth noting is that all of the domains that only use the mail server mail.c.sweetheart.cc use name server group 2.
