We pick j.root-servers.net, one of the 13 root servers (1), and ask it about 81.199.251.205.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask d.in-addr-servers.arpa where we learn that 205.in-addr.arpa is delegated to eight name servers, including v.arin.net (3), so we ask that one and learn that 199.251.205.in-addr.arpa is delegated to three name servers (4), so we ask ns-3.amazon.com and get the following answer:
