We pick k.root-servers.net, one of the 13 root servers (1), and ask it about ns.net.au and learn that au is delegated to eleven name servers (2), so we ask u.au where we learn that net.au is delegated to four name servers, including w.au (3), so we ask that one and learn that ns.net.au is delegated to four name servers (4), so we ask ns4.routed.org and get the following answer:
Ns.net.au is a domain controlled by four domain name servers at routed.org having a total of four IP numbers. There are four duplicated IP numbers. All four of them are on different IP networks.
