We pick d.root-servers.net, one of the 13 root servers (1), and ask it about petrushin.ru and learn that ru is delegated to five name servers (2), so we ask a.dns.ripn.net where we learn that petrushin.ru is delegated to two name servers, including ns1.k-a-z-a-n.ru (3), so we ask that one and get the following answer:
All of the five domains that use the primary name server ns1.k-a-z-a-n.ru use name server group 1. Worth noting is that five of the domains that use name server group 1 use the primary name server ns1.k-a-z-a-n.ru.
The two name servers ns1 and ns2.k-a-z-a-n.ru together
There are six domains that use name server group 1.
All of those are under the tld "ru".
All of them use only the IPv4 number 79.174.72.87. Worth noting is that six of the domains that only use the IPv4 number 79.174.72.87 use name server group 1.
All of them point only to the IP number 79.174.72.87.
The IPv4 number 79.174.72.87 only
There are about ninety domains that only use the IPv4 number 79.174.72.87.
