Read the IPCHAINS HOWTO. I think you can do something like:
ipchains -A input -s ad.doubleclick.net -j DENY
ipchains -A output -d ad.doubleclick.net -j DENY
You probably want to tailor the above to meet your needs.
This will block *any* kind of connection to/from that site, although DNS
lookups will still work. Your browser will probably complain of timeout
connecting to that site or something. I'm not quite sure about a cleaner
