There are a few approaches you could take, and it depends on what you are trying to do.

If you are actually trying to block traffic to a specific server/servers, I'd say use a firewall.  If you're running on a linux box, it's pretty easy:

Failing that, I believe there is a bind directive (blackhole) that might do what you want, but I've never looked into it.

Finally, if you are simply trying to block certain domains, you could load them as master zones on your server and leave them blank.

Cheers,

Todd.
