3203.192.in-addr.arpa.192.in-addr.arpa.(w,v,y,x,t,z,r,u).arin.net.
We pick e.root-servers.net, one of the 13 root servers (1), and ask it about 203.192.in-addr.arpa and learn that in-addr.arpa is delegated to six name servers (2), so we ask d.in-addr-servers.arpa where we learn that 192.in-addr.arpa is delegated to eight name servers, including w.arin.net (3), so we ask that one and get the following answer:
