The Airport Extreme access point/router acts as a DNS server for your 
local network and then it forwards queries to the actual DNS servers.  
To see the actual ones, you could look in the Airport utility or, if you 
want to use Wireshark, you will need a hub or Ethernet tap and connect 
it in between the Airport and the DSL modem.
