How AdGuard DNS works

Let's imagine that you've connected your devices to AdGuard DNS. Now your DNS service is up and running.

Every time you enter a website URL or open a link, your device asks AdGuard DNS for the corresponding IP address.

If the domain address belongs to an advertising, tracking, malicious, or phishing website, AdGuard DNS blocks your access to it, thus protecting you from malicious attacks or privacy breaches.

Our dashboard gives you a clear understanding of what domains get requested by each of your devices. It helps you quickly and easily block unwanted sites.

You're all set! AdGuard DNS helps you control your online experience and see what you want to see without exposure to ads, tracking, or malicious threats.

Features

Ad blocking

AdGuard DNS uses powerful filters to eliminate ads and trackers on every connected device. Trust our default filters, block domains manually, or do both: it’s up to you.

FAQ

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.

What are DoH and DoT?

They are modern secure DNS protocols that gain more and more popularity and will become the industry standards for the foreseeable future. Both are more reliable than DNSCrypt and both are supported by AdGuard DNS.

What is DoQ?

DNS-over-QUIC is a new DNS encryption protocol and AdGuard DNS is the first public resolver that supports it. So what's good about it? Unlike DoH and DoT, it uses QUIC as a transport protocol and finally brings DNS back to its roots — working over UDP. It brings all the good things that QUIC has to offer — out-of-the-box encryption, reduced connection times, better performance when data packets are lost. Also, QUIC is supposed to be a transport-level protocol and there are no risks of metadata leaks that could happen with DoH.

What is DNSSEC?

AdGuard DNS supports DNSSEC technology which allows you to verify the authenticity of the stored DNS records with a digital signature. It provides protection against current and potential attacks on DNS queries and responses aiming to forge them or change their content, and at the same time it fends off other online threats.

Why is AdGuard DNS free?

You can use public AdGuard DNS servers for free — there's no catch. However, we incorporate AdGuard DNS in many paid AdGuard and AdGuard VPN apps. We also offer paid personal AdGuard DNS servers with advanced functionality and more customization options.

What devices can I use AdGuard DNS with?

There are no restrictions for which devices you can use it with. You can find a separate configuration manual for each platform on this page.

What ports does AdGuard DNS use?

AdGuard DNS uses default port 53. In case port 53 is blocked or unavailable, use port 5353 instead.

I have some troubles or questions that are not covered by this FAQ. What do I do?

You will find everything related to AdGuard DNS on GitHub, or you can just ask us by contacting our support: support@adguard-dns.io. We will answer you as soon as possible.
