We pick k.root-servers.net, one of the 13 root servers (1), and ask it about mx.reic.ru and learn that ru is delegated to five name servers (2), so we ask f.dns.ripn.net where we learn that reic.ru is delegated to two name servers, including ns2.reic.ru (3), so we ask that one and get the following answer:
Mx.reic.ru is a domain controlled by two domain name servers at reic.ru. Both are on different IP networks. Incoming mail for mx.reic.ru is handled by two mail servers also at reic.ru. Both are on the same IP network. Mx.reic.ru has one IP number (87.236.18.104), but the reverse is mx1.reic.ru.
