We pick j.root-servers.net, one of the 13 root servers (1), and ask it about 50.64.91.80.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask a.in-addr-servers.arpa where we learn that 80.in-addr.arpa is delegated to six name servers, including ns3.nic.fr (3), so we ask that one and learn that 64.91.80.in-addr.arpa is delegated to four name servers (4), so we ask auth4.dns.cogentco.com and get the following answer:
