We pick f.root-servers.net, one of the 13 root servers (1), and ask it about dns-master.ru and learn that ru is delegated to five name servers (2), so we ask b.dns.ripn.net where we learn that dns-master.ru is delegated to three name servers, including ns7.nic.ru (3), so we ask that one and get the following answer:
Dns-master.ru is hosted on a server in Russian Federation.
The IP number 194.85.61.42
There are nine host names that point to the IP number 194.85.61.42.
All of those point only to that ip number (example: *.hi-laser.com ).
Three of them use the name server ns7.nic.ru. Worth noting is that three of the domains that use the name server ns7.nic.ru point to the IP number 194.85.61.42.
Three of them use the name server ns6.nic.ru. Worth noting is that three of the domains that use the name server ns6.nic.ru point to the IP number 194.85.61.42.
The name server ns6.nic.ru
There are about eighty domains that use the name server ns6.nic.ru.
Three of them point to the IP number 194.85.61.42. Worth noting is that three of the host names that point to the IP number 194.85.61.42 use the name server ns6.nic.ru.
The three name servers ns5, ns6 and ns7.nic.ru together
