We pick g.root-servers.net, one of the 13 root servers (1), and ask it about 42.187.201.173.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask b.in-addr-servers.arpa where we learn that 173.in-addr.arpa is delegated to eight name servers, including u.arin.net (3), so we ask that one and learn that 201.173.in-addr.arpa is delegated to three name servers (4), so we ask cns3.secureserver.net and get the following answer:
