We pick h.root-servers.net, one of the 13 root servers (1), and ask it about hotmail.org.pe and learn that pe is delegated to three name servers (2), so we ask pe1.dnsnode.net where we learn that hotmail.org.pe is delegated to three name servers, including ns1.msft.net (3), so we ask that one and get the following answer:
The two IP numbers 64.4.6.100 and 65.55.39.10 together
There are several thousand of host names that point to IP group 1.
Three quarter of those use name server group 1 (example: responsiva.com, xboxmultiplayer.com and msn-updater.net ). Worth noting is that a third of the domains that use name server group 1 point to IP group 1.
Nine percent of them use name server group 2 (example: msnvideo.se, win-met-office365.be and mywindows.se ). Worth noting is that a third of the domains that use name server group 2 point to IP group 1.
The five name servers ns1, ns2, ns3, ns4 and ns5.msft.net together
A third of the several thousand of domains that use name server group 1 point to IP group 1 (example: ee-messenger.net, accounts-passport.us and nameofmycompany.com ). Worth noting is that two thirds of the host names that point to IP group 1 use name server 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 (example: windows07.se ). Worth noting is that six percent of the host names that point to IP group 1 use name server group 2.
