420.50.in-addr.arpa.20.50.in-addr.arpa.(infinity,beyond).cbeyond.net.
We pick d.root-servers.net, one of the 13 root servers (1), and ask it about 20.50.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 50.in-addr.arpa is delegated to eight name servers, including v.arin.net (3), so we ask that one and learn that 20.50.in-addr.arpa is delegated to two name servers (4), so we ask infinity.cbeyond.net and get the following answer:
