We pick g.root-servers.net, one of the 13 root servers (1), and ask it about au.net and learn that net is delegated to 13 name servers (2), so we ask a.gtld-servers.net where we learn that au.net is delegated to two name servers, including ns1.gnusto.com (3), so we ask that one and get the following answer:
There are five domains that use the name server ns1.gnusto.com.
All of those point to the IP number 203.133.248.2. Worth noting is that five of the host names that point to the IP number 203.133.248.2 use the name server ns1.gnusto.com.
Four of them use the two name servers ns1.gnusto.com and sec1.apnic.net together, hereafter referred to as "name server group 1".
The two name servers ns1.gnusto.com and sec1.apnic.net together
Three of the four domains that use name server group 1 point only to the IP number 203.133.248.2. Worth noting is that three of the host names that point only to the IP number 203.133.248.2 use name server group 1.
The IP number 203.133.248.2
There are about twenty host names that point to the IP number 203.133.248.2.
Five of them use the name server sec1.apnic.net. Worth noting is that three of the domains that use the name server sec1.apnic.net point to the IP number 203.133.248.2.
Five of them use the name server ns1.gnusto.com. Worth noting is that all of the domains that use the name server ns1.gnusto.com point to the IP number 203.133.248.2.
The name server sec1.apnic.net
There are several hundred of domains that use the name server sec1.apnic.net.
