We pick d.root-servers.net, one of the 13 root servers (1), and ask it about e.mu and learn that mu is delegated to four name servers (2), so we ask udns2.tld.mu where we learn that e.mu is delegated to two name servers, including ns1.vodrv.net (3), so we ask that one and get the following answer:
E.mu is a domain controlled by two domain name servers at vodrv.net. Both are on the same IP network. Incoming mail for e.mu is handled by one mail server at e.mu themselves. E.mu has one IP number (207.58.134.192), but the reverse is host.vodrv.net.
Four of them point to the IP number 207.58.134.192. Worth noting is that four of the host names that point to the IP number 207.58.134.192 use the name server ns2.vodrv.net.
The IP number 207.58.134.192
There are nine host names that point to the IP number 207.58.134.192.
All of those point only to that ip number (example: *.mtn.co.af ).
Four of them use the name server ns2.vodrv.net. Worth noting is that four of the domains that use the name server ns2.vodrv.net point to the IP number 207.58.134.192.
Four of them use the name server ns1.vodrv.net. Worth noting is that four of the domains that use the name server ns1.vodrv.net point to the IP number 207.58.134.192.
The two name servers ns1 and ns2.vodrv.net together
Six of the eleven domains that use name server group 1 point only to the IP number 207.58.136.19.
