We pick j.root-servers.net, one of the 13 root servers (1), and ask it about 254.0.81.209.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask c.in-addr-servers.arpa where we learn that 209.in-addr.arpa is delegated to eight name servers, including w.arin.net (3), so we ask that one and learn that 0.81.209.in-addr.arpa is delegated to two name servers (4), so we ask ns2.via.net and get the following answer:
