DNS delegation of zerkalo.az updated: May 24, 2013 4:39:19 PM
ns.demos.su. az.hostmaster.ua. rip.psg.com.
We pick j.root-servers.net, one of the 13 root servers (1), and ask it about zerkalo.az and learn that az is delegated to three name servers (2), so we ask ns.demos.su where we learn that zerkalo.az is delegated to three name servers, including ns3.online.az (3), so we ask that one and get the following answer:
Zerkalo.az is a domain controlled by three domain name servers at online.az. Two of them are on the same IP network. Incoming mail for zerkalo.az is handled by one mail server at zerkalo.az themselves having a total of two IP numbers. Both are on different IP networks. Zerkalo.az has one IP number (22.214.171.124), which also has a corresponding reverse pointer.
