forcing different dns server for specific domains

HI guys,

What i m trying to figure out is how to use specific dns servers for specific domain querys, using the firewall. I don t have a proxy installed on my CCR1016, and i don t use any external proxy as well.
I m using Nortons public dns server to filter out adult content websites, but what basically happens is that sometimes i get false positive blocks, for google drive’s subdomains. (ex: oc-00-4s-docs.googleusercontent.com )

Is it possible to use the L7-protocol to tell my router to use a diffrent dns ip for the following subdomains : XXXXX.googleusercontent.com ?

I know that a proper way would be using a transparent proxy to do the website filtering, but i m looking for a temporary solution.

Any input regarding this would be appreciated.
Steve

Yes you can, plus some extra useful info is in this thread.

hi,
I will recommend to use opendns their DNS server response is quick, we can block contents category wise also we can block/allow specific domains.
