We pick j.root-servers.net, one of the 13 root servers (1), and ask it about hotmail.kr and learn that kr is delegated to six name servers (2), so we ask f.dns.kr where we learn that hotmail.kr is delegated to three name servers, including ns3.msft.net (3), so we ask that one and get the following answer:
The five name servers ns1, ns2, ns3, ns4 and ns5.msft.net together
There are several thousand of domains that use name server group 1.
Half of those point to IP group 1 (example: msn-activate.biz, msncards.net and windowslivereviews.com ). Worth noting is that three quarter of the host names that point to IP group 1 use name server group 1.
Five percent of them point to IP group 3.
The two IP numbers 64.4.6.100 and 65.55.39.10 together
Three quarter of the several thousand of host names that point to IP group 1 use name server group 1 (example: microsoftwebs.com, msnmessenger2008.com and 121hotmailhelp.com ). Worth noting is that half of the domains that use name server group 1 point to IP group 1.
The three name servers ns1, ns3 and ns4.msft.net together
A third of the more than a thousands domains that use name server group 2 point to IP group 1.
