AdGuard DNS filter

Formerly AdGuard Simplified Domain names filter.

A filter composed of several other filters (AdGuard Base filter, Social media filter, Tracking Protection filter, Mobile Ads filter, EasyList and EasyPrivacy) and simplified specifically to be better compatible with DNS-level ad blocking.

The direct link to the filter: https://adguardteam.github.io/AdGuardSDNSFilter/Filters/filter.txt.

Please note, that to use this filter it is necessary to support basic ad blocking rules syntax. It does not make much sense to extract just the hosts file.

This is a default filter for AdGuard Home and for the public AdGuard DNS servers.

How to build AdGuard DNS filter manually

yarn install
yarn run build

AdGuard DNS Popup Hosts filter

DNS-level blocking is a crude method that makes a blocked website appear as if it were malfunctioning from the user's perspective. While this approach may suffice for blocking sub-requests to trackers, it is less effective when a user attempts to access a blocked domain directly.

This filter blocks domains that the users tend to open (more precisely, they are opened against the users' will) and it redirects them to a designated "blocked page", which provides explanations regarding the reasons for blocking.

Although redirecting to a different IP address is not the ideal solution, we are hopeful that the Structured Errors proposal will gain momentum. This would allow us to implement a better solution.

AdGuard DNS Popup Hosts filter structure

The AdGuard DNS Popup Hosts filter includes only rules that contain the modifiers popup, all, and document from the lists provided. This selection effectively means that these rules are directed at sites that open in the main frame.
