DNS delegation of hotmail.ru updated: May 18, 2013 11:53:46 PM
We pick c.root-servers.net, one of the 13 root servers (1), and ask it about hotmail.ru and learn that ru is delegated to five name servers (2), so we ask f.dns.ripn.net where we learn that hotmail.ru is delegated to three name servers, including ns3.pochta.ru (3), so we ask that one and get the following answer:
Hotmail.ru is a domain controlled by three domain name servers at pochta.ru. Two of them are on the same IP network. Incoming mail for hotmail.ru is handled by one mail server at qip.ru having a total of five IP numbers. All five of them are on the same IP network. Hotmail.ru has two IP numbers (22.214.171.124, 126.96.36.199). Both are on the same IP network.
The three name servers ns1, ns2 and ns3.pochta.ru together
All of the about twenty domains that use name server group 1 point to the two IP numbers 188.8.131.52 and 184.108.40.206 together, hereafter referred to as "IP group 1", (example: mail15.su, fromru.su and pisem.su ). Worth noting is that a third of the host names that point to IP group 1 use name server group 1.
The two IP numbers 220.127.116.11 and 18.104.22.168 together
A third of the about sixty host names that point to IP group 1 use only the mail server mx.qip.ru (example: mail.qip.ru ).
