How to stop web tracking scripts from using proxies

Advanced advertisers hide their tracking scripts (like Google Analytics) behind subdomains designed to mimic legitimate parts of the site you're visiting (CNAME cloaking), effectively bypassing traditional ad-block blacklists.

Network signature analysis against CNAME cloaking

Static filter lists fail against local logical subdomains. AdBlock Network solves this by performing network signature analysis. The extension executes asynchronous, read-only requests to multiple independent endpoints to refresh its firewall, allowing the Advanced layer to block connections to cloaked proxy servers.
