We pick a.root-servers.net, one of the 13 root servers (1), and ask it about ns2.az and learn that az is delegated to three name servers (2), so we ask az.hostmaster.ua where we learn that ns2.az is delegated to two name servers, including ns2.dot.az (3), so we ask that one and get the following answer:
Ns2.az is a domain controlled by two domain name servers at dot.az. Both are on the same IP network. Incoming mail for ns2.az is handled by one mail server at ns2.az themselves. Ns2.az has one IP number (94.20.94.141), but the reverse is azvirt.com.
All of the about twenty domains that use the name server ns2.dot.az use the two name servers ns1 and ns2.dot.az together, hereafter referred to as "name server group 1", (example: talibov.com, sahhat.az and v-motors.com ).
The name server ns2.az
All of the four domains that use the name server ns2.az use the two name servers ns1 and ns2.az together.
The IP number 94.20.94.141
All of the seven host names that point to the IP number 94.20.94.141 point only to that ip number.
The two name servers ns1 and ns2.dot.az together
Three quarter of the about twenty domains that use name server group 1 point only to the IP number 94.20.94.140 (example: dot.az, elchin.net and smile.az ).
