We pick l.root-servers.net, one of the 13 root servers (1), and ask it about 25.103.154.156.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 154.156.in-addr.arpa is delegated to six name servers, including pdns5.ultradns.info (3), so we ask that one and get the following answer:
