We pick k.root-servers.net, one of the 13 root servers (1), and ask it about 20.253.167.168.in-addr.arpa and learn that arpa is delegated to twelve name servers (2), so we ask k.root-servers.net where we learn that in-addr.arpa is delegated to six name servers, including b.in-addr-servers.arpa (3), so we ask that one and learn that 168.in-addr.arpa is delegated to eight name servers (4), so we ask u.arin.net and learn that 167.168.in-addr.arpa is delegated to three name servers (5), so we ask ns1.btc.bw and get the following answer:
