Maybe adsuck would be a good tool for what you want.

It original purpose it to use lists of blacklisted hosts to redirect 
them to by using the dns system and stop ads in browing. 
adsuck uses files with the same syntax as /etc/hosts and then if it 
doesn't know the name if will pass the request to your DNS resolver.
