We pick k.root-servers.net, one of the 13 root servers (1), and ask it about m.is and learn that is is delegated to seven name servers (2), so we ask isgate.is where we learn that m.is is delegated to two name servers, including dns2.isb.is (3), so we ask that one and get the following answer:
M.is is a domain controlled by two domain name servers at isb.is. Both are on the same IP network. Incoming mail for m.is is handled by three mail servers also at isb.is. All three of them are on the same IP network. M.is has one IP number (194.105.248.109), but the reverse is isb109.isb.is.
M.is is hosted on a server in Reykjavík, 10, Iceland.
The name server dns2.isb.is
All of the about twenty domains that use the name server dns2.isb.is use the two name servers dns1 and dns2.isb.is together.
The mail server mx3.isb.is
There are about twenty domains that use the mail server mx3.isb.is.
All of those use the three mail servers mx01, mx02 and mx3.isb.is together.
Six of them point to the IP number 194.105.248.109. Worth noting is that six of the host names that point to the IP number 194.105.248.109 use the mail server mx3.isb.is.
The IP number 194.105.248.109
There are 13 host names that point to the IP number 194.105.248.109.
Six of them use the name server dns2.isb.is. Worth noting is that six of the domains that use the name server dns2.isb.is point to the IP number 194.105.248.109.
Six of them use the name server dns1.isb.is. Worth noting is that six of the domains that use the name server dns1.isb.is point to the IP number 194.105.248.109.
