We pick k.root-servers.net, one of the 13 root servers (1), and ask it about 20.1.86.128.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 86.128.in-addr.arpa is delegated to five name servers, including ns2.ja.net (3), so we ask that one and get the following answer:
