We pick h.root-servers.net, one of the 13 root servers (1), and ask it about ns4.mybcshop.com and learn that com is delegated to 13 name servers (2), so we ask e.gtld-servers.net where we learn that mybcshop.com is delegated to two name servers, including ns1.above.com (3), so we ask that one and get the following answer:
Ns4.mybcshop.com is a domain controlled by two domain name servers at above.com having a total of four IP numbers. Some of them are on the same IP network. Ns4.mybcshop.com has one IP number (69.43.161.173), which is the same as for mybcshop.com, but the reverse is ?.
All of the several thousand of domains that use the primary name server ns1.above.com use name server group 1 (example: www.ouzoku.com, callofthegods.com and tamoliado.net ). Worth noting is that three quarter of the domains that use name server group 1 use the primary name server ns1.above.com.
The IPv4 number 69.43.161.173 only
There are several thousand of domains that only use the IPv4 number 69.43.161.173.
