(ns2,ns3,ns1).domaindiscount24.net.
We pick g.root-servers.net, one of the 13 root servers (1), and ask it about wwww.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that wwww.com is delegated to three name servers, including ns2.domaindiscount24.net (3), so we ask that one and get the following answer:
The three name servers ns1, ns2 and ns3.domaindiscount24.net together
One quarter of the several thousand of domains that use name server group 1 point to IP group 1 (example: heels2.com, world-w.com and net-reisen.net ). Worth noting is that a third of the host names that point to IP group 1 use name server group 1.
The three IP numbers 109.234.109.20, 109.234.109.21 and 213.128.138.236 together
There are several thousand of host names that point to IP group 1.
A third of those use name server group 1 (example: flyengine.com, isits.net and ruedinger.biz ). Worth noting is that one quarter of the domains that use name server group 1 point to IP group 1.
