alternately ...
if you run a local DNS, add a new primary zone for doubleclick.net and don't
add any entries to the domain beyond the SOA and DNS ...
if you don't run a local DNS, add things like ad.doubleclick.net to your
hosts file and point them to localhost or 127.0.0.1
should ease things up, tho YMMV
