We pick i.root-servers.net, one of the 13 root servers (1), and ask it about 12.4.33.192.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask e.in-addr-servers.arpa where we learn that 192.in-addr.arpa is delegated to eight name servers, including r.arin.net (3), so we ask that one and learn that 4.33.192.in-addr.arpa is delegated to four name servers (4), so we ask auth4.dns.cogentco.com and get the following answer:
