We pick b.root-servers.net, one of the 13 root servers (1), and ask it about ns1.me and learn that me is delegated to eight name servers (2), so we ask c0.cctld.afilias-nst.info where we learn that ns1.me is delegated to four name servers, including ns1.me (3), so we ask that one and get the following answer:
Ns1.me is a domain controlled by three domain name servers at ns1.me, ns2.org.uk and ns0.us having a total of four IP numbers. All four of them are on different IP networks. We are missing the IP:s of one server: ns0.us. Incoming mail for ns1.me is handled by one mail server at ns1.me themselves having a total of two IP numbers. Both are on different IP networks. Ns1.me has two IP numbers (213.5.94.30, 2001:67c:1b8:100e::30). Both are on different IP networks.
Ns1.me is hosted on two servers in United Kingdom even though the hostname implies Montenegro.
The two name servers ns1 and ns2.me together
All of the three domains that use the two name servers ns1 and ns2.me together, hereafter referred to as "name server group 1", point only to the IP number 198.101.239.80.
The name server ns0.us
There are 13 domains that use the name server ns0.us.
