Well, I don't know about using a negation, but it seems to me that as
long as you have a gateway address entered in your network
configuration, unresolved addresses (DNS requests as well as any other
IP packet bearing an outside world address) will be sent to the
gateway (a router or the Qube if it is the one connected to the
Internet) if it cannot be resolved locally.
Putting a secondary DNS might generate a lot of sync traffic between
your DNS and the secondary.
Also, if the gateway address is setup in every computer on your LAN,
they will access the Internet if they cannot find the address locally.
DNS requests will be forwarded to your ISP DNS that is most probably
setup in your router config (or Qube if it is the one acting as
modem-router).
HTH.
