We pick b.root-servers.net, one of the 13 root servers (1), and ask it about 2.5.8.128.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask f.in-addr-servers.arpa where we learn that 128.in-addr.arpa is delegated to eight name servers, including w.arin.net (3), so we ask that one and learn that 8.128.in-addr.arpa is delegated to three name servers (4), so we ask ns2.umd.edu and get the following answer:
