We pick g.root-servers.net, one of the 13 root servers (1), and ask it about onet.com.au and learn that au is delegated to eleven name servers (2), so we ask u.au where we learn that com.au is delegated to four name servers, including w.au (3), so we ask that one and learn that onet.com.au is delegated to two name servers (4), so we ask ns2.exetel.com.au and get the following answer:
Onet.com.au is a domain controlled by two domain name servers at exetel.com.au. Both are on the same IP network. Incoming mail for onet.com.au is handled by two mail servers also at exetel.com.au. Both are on the same IP network.
