Adguard DNS is an alternative way to block ads, trackers and phishing websites, and also a parental control instrument. ### How does Adguard DNS work? If you configure your network to use our DNS servers, every time a website sends an ad or phishing request, our server sends back a null response. Adguard has a database of domain names that serve for ad, tracking or phishing purposes, and this database is regularly updated. Adguard DNS works in two modes: 'Default' mode includes blocking ads, various trackers and malware & phishing websites. 'Family protection' does the same, but also blocks websites with adult content. This repository contains filters used by Adguard DNS server. ### How to use Adguard DNS? The detailed guide can be found on [our website](https://test.adguard.com/en/adguard-dns/instruction.html#instruction). If you come across any problems or have a suggestion, feel free to create an issue in this repository. ### What's next? We plan to make Adguard DNS open source in the near future.
