We pick b.root-servers.net, one of the 13 root servers (1), and ask it about ns3.tv and learn that tv is delegated to seven name servers (2), so we ask f5.nstld.com where we learn that ns3.tv is delegated to two name servers, including buy.internettraffic.com (3), so we ask that one and get the following answer:
Ns3.tv is a domain controlled by two domain name servers at internettraffic.com having a total of four IP numbers. Some of them are on the same IP network. Ns3.tv has two IP numbers (176.74.176.167, 208.87.35.103). Both are on different IP networks.
The two name servers buy and sell.internettraffic.com together
There are several thousand of domains that use name server group 1.
Two thirds of those point to IP group 1 (example: nebulizermachines.com, welchallyninc.com and nona.com ). Worth noting is that three quarter of the host names that point to IP group 1 use name server group 1.
The two IP numbers 176.74.176.167 and 208.87.35.103 together
Three quarter of the several thousand of host names that point to IP group 1 use name server group 1 (example: trav.it, uqfb.com and sexcrime.net ). Worth noting is that one quarter of the domains that use name server group 1 point to IP group 1.
