We pick b.root-servers.net, one of the 13 root servers (1), and ask it about bacninh.com and learn that com is delegated to 13 name servers (2), so we ask l.gtld-servers.net where we learn that bacninh.com is delegated to two name servers, including ns2.matbao.com (3), so we ask that one and get the following answer:
Bacninh.com is a domain controlled by two domain name servers at matbao.com. Both are on different IP networks. Incoming mail for bacninh.com is handled by five mail servers at googlemail.com and google.com having a total of 51 IP numbers. There are eleven duplicated IP numbers. Some of them are on the same IP network. Bacninh.com has one IP number (112.78.2.99), but the reverse is mb2d99.vdrs.net.
