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 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/).
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.
