We pick g.root-servers.net, one of the 13 root servers (1), and ask it about 142.140.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask a.in-addr-servers.arpa where we learn that 140.in-addr.arpa is delegated to eight name servers, including w.arin.net (3), so we ask that one and learn that 142.140.in-addr.arpa is delegated to three name servers (4), so we ask hanna.cac.washington.edu and get the following answer:
