We pick j.root-servers.net, one of the 13 root servers (1), and ask it about 1.42.16.172.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 172.in-addr.arpa is delegated to eight name servers, including w.arin.net (3), so we ask that one and learn that 16.172.in-addr.arpa is delegated to two name servers (4), so we ask blackhole-2.iana.org and get the following answer:
