We pick c.root-servers.net, one of the 13 root servers (1), and ask it about 57.100.249.80.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 80.in-addr.arpa is delegated to four name servers, including sns-pb.isc.org (3), so we ask that one and learn that 100.249.80.in-addr.arpa is delegated to three name servers (4), so we ask ns1.ncuk.net and get the following answer:
