We pick a.root-servers.net, one of the 13 root servers (1), and ask it about 72.248.212.144.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 144.in-addr.arpa is delegated to eight name servers, including y.arin.net (3), so we ask that one and learn that 212.144.in-addr.arpa is delegated to four name servers (4), so we ask ns.mathworks.com and get the following answer:
