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 blocks 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. #### DNSCrypt AdGuard supports DNSCrypt — a special protocol that encrypts communication with the DNS server, thus preventing tampering and tracking by any third party, including your ISP. Read more about DNSCrypt [here](https://dnscrypt.org/). ### How to use AdGuard DNS? The detailed guide can be found on [our website](https://adguard.com/en/adguard-dns/instruction.html#instruction). If you come across any problem, or have a suggestion, head to [this page](https://github.com/AdguardTeam/AdguardDNS/issues) and click on the *New issue* button. ### What's next? We plan to make AdGuard DNS open source in the near future.
