This repository contains lists of domains that very likely serve ads, analytics scripts, tracking pixels, widgets (webpage plugins), content enrichment (begging for mail subscription, sharing abilities), and represent affiliate or fake webpages. Usually lists get at least a monthly update.

Domains have been manually gathered by looking at dns requests, javascript and html code in the past 16 years and put into categories where they mostly belong. Note: Although some domains could fit into two or more categories they are listed in only one. Since domains are not automatically added, high quality (fewer false positives) could be guaranteed.

Please submit any additions, corrections or comments by using issue or pull request.

Beginning in 2026, the misc.txt list is generated by a predictive algorithm known as DNS Doctor and predominantly includes domains that are candidates for future inclusion in ads.txt and analytics.txt.

In addition, non-existent or unresolvable domains are systematically excluded from all lists.

Each list or a concatenated list must be additionally adapted to be used as hosts file or by dnsmasq, bind or any other dns server software or web filtering solution.

You are free to copy and distribute any of these lists for non-commercial uses as long the original URL is included.
