AdGuard DNS — ad-blocking DNS server

What is DNS?

DNS stands for Domain Name System. Think of it as of "address book" of the Internet: your browsers and apps use it to translate domain names that make no sense to them into IP addresses that they can understand.

What is AdGuard DNS?

AdGuard DNS is a free, privacy-oriented ad-block DNS server. In addition to resolving DNS requests, it blocks ads, trackers, and malicious domains. You can use it instead of your current DNS provider.

How does AdGuard DNS work?

When you use AdGuard DNS, every time your browser or app sends an inappropriate DNS request, our DNS server sends back a null response instead of an IP address. To prevent ads, tracking, and fraud, AdGuard DNS uses a frequently updated database of domain names.

What can AdGuard DNS do?

It has three different modes, depending on which server addresses you use. "Default" mode is for blocking ads, trackers, malware and phishing websites. "Family protection" does the same, but also blocks websites with adult content and enforces "Safe search" option in browsers that provide it. "Non-filtering" provides a secure and reliable connection but doesn't block anything.

What makes AdGuard DNS privacy-oriented?

AdGuard DNS takes several measures to ensure your privacy. It supports all popular secure DNS communication protocols: DNSCrypt, DNS-over-HTTPS (DoH), DNS-over-TLS (DoT), and DNS-over-QUIC (DoQ).

What is DNSCrypt?

Instead of a regular client-server interaction protocol, AdGuard DNS allows you to use a specific encrypted protocol — DNSCrypt. Thanks to it, all DNS requests are being encrypted, which protects you from possible request interception and subsequent eavesdropping and/or alteration.

Does AdGuard DNS work in all browsers and apps?

Yes, due to the nature of how DNS works, all DNS traffic of your device will go through AdGuard.

How to configure AdGuard DNS?

The instructions on how to configure AdGuard DNS on different operating systems will vary. Go to Setup guide, find the one suitable for your case, and follow it to configure AdGuard DNS on your device.
