Re: Add an Ad Blocker on the router too?
Run your own ISC BIND server internally and use Response Policy Zones to blacklist all known advertising/tracking sites so all the crud on the web page will never be resolved.
Even if you run your own DNS Server remember it still has to go out and perform the initial query which is then cached for the TTL of the DNS record. So it is visible upstream if the ISP is performing DNS traffic recording. What will be more difficult is to determine how many times you access an individual page on the web site.
