We pick i.root-servers.net, one of the 13 root servers (1), and ask it about m.ac.nz and learn that nz is delegated to seven name servers (2), so we ask ns6.dns.net.nz where we learn that m.ac.nz is delegated to three name servers, including s3.dns.m.ac.nz (3), so we ask that one and get the following answer:
M.ac.nz is a domain controlled by three domain name servers at m.ac.nz themselves. All three of them are on different IP networks. Incoming mail for m.ac.nz is handled by seven mail servers at googlemail.com and google.com having a total of 53 IP numbers. There are 30 duplicated IP numbers. Some of them are on the same IP network. M.ac.nz has one IP number (64.207.137.52), but the reverse is acsmekgqcc.gs10.mtsvc.net.

The IP number 64.207.137.52
All of the five host names that point to the IP number 64.207.137.52 point only to that ip number.
