We pick g.root-servers.net, one of the 13 root servers (1), and ask it about 7.209.16.204.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 204.in-addr.arpa is delegated to eight name servers, including v.arin.net (3), so we ask that one and learn that 209.16.204.in-addr.arpa is delegated to six name servers (4), so we ask dns6.ciscoeos.com and get the following answer:
