We pick h.root-servers.net, one of the 13 root servers (1), and ask it about nsv.ru and learn that ru is delegated to five name servers (2), so we ask a.dns.ripn.net where we learn that nsv.ru is delegated to three name servers, including ns.naukanet.ru (3), so we ask that one and get the following answer:
Nsv.ru is a domain controlled by three domain name servers at naukanet.ru having a total of five IP numbers. Two of them are on the same IP network. Incoming mail for nsv.ru is handled by two mail servers also at naukanet.ru. Both are on different IP networks. Nsv.ru has one IP number (84.47.177.101), but the reverse is www.naukanet.ru.
