Mullvad DNS is a private and secure DNS service that helps protect your online identity.
It's a Swedish-based company that has been in the business of protecting user data since 2003.
Mullvad DNS is designed to keep your DNS queries private, meaning your internet service provider (ISP) can't see what websites you're visiting.
This is especially important for users who value their online anonymity and security.

Content Blocking
Mullvad DNS offers a range of hostname options with built-in content blockers.
You can refer to the table below to see the different hostname options and their corresponding content blockers.
Mullvad curates its content blocking lists from publicly available block lists, which are sourced from community lists on GitHub.
This means that if a hostname matches an item in the block list, the Mullvad resolver will lie to the client and say the hostname doesn't exist.
As a result, any content attempted to be loaded by the browser won't be loaded and won't be shown on the screen.

Web Browsers
Mullvad DNS is a great service, but you might be wondering how to configure it in your web browser. The good news is that it's relatively easy.
To change the DNS options in your browser, you'll need to access the browser settings. In most browsers, this can be done by clicking on the menu button in the top right corner and selecting Settings. From there, you'll need to click on Privacy & Security in the left column.
To use the Mullvad DNS service, you'll need to select Max Protection from the Enable secure DNS using dropdown list. Then, click on Custom from the Choose provider dropdown list and paste one of the following into the text field: Mullvad DNSCloudflare DNSGoogle DNS
It's worth noting that if you're connected to Mullvad VPN, you shouldn't use the Mullvad DNS service.

Web Browsers
If you're using Mullvad VPN, you'll want to turn off DNS over HTTPS, which you can do by following these steps:

Click on the menu button in the top right corner and select Settings.
Scroll down to the bottom of the Privacy & Security page.
Under Enable secure DNS using, select Max Protection.
Under Choose provider, click on the drop down list and select Custom.

The Mullvad Browser uses the Mullvad DNS service by default, but it's recommended to use it only when not connected to Mullvad VPN. When connected to Mullvad VPN, DNS queries are sent through the encrypted VPN tunnel to the DNS server on the Mullvad VPN server.
Many web browsers, including Chrome-based browsers, have a setting for enabling or disabling DNS over HTTPS, which is called Secure DNS.

The App
The Mullvad VPN app is a good example of how a well-designed app can protect your online security.

It protects you from DNS leaks, unless you enable the Use custom DNS server option in the app settings.
This means that Mullvad's default settings keep you safe from DNS leaks, which can compromise your online security.
To verify if the app is working correctly, you can use a command to check for DNS leaks.

Linux
Linux users can easily set up Mullvad DNS on their systems. The instructions for Ubuntu and Fedora use systemd-resolved.
To get started, make sure you're using systemd-resolved, as it's required for Mullvad DNS to work. If you're not using it, you can change your setting in /etc/systemd/resolved.conf to DNSOverTLS=opportunistic.
Some websites may not load correctly if they have incorrect DNSSEC information, so be aware of this potential issue. However, you can still enable DNSSEC if you want to.

Security & Networking
Linux users can configure Mullvad's Encrypted DNS by changing the DNSOverTLS setting in /etc/systemd/resolved.conf to opportunistic.
Some third-party apps have built-in DNS hijacking capabilities, so it's essential to be cautious when using them.
To check if encrypted DNS is working, you can visit Mullvad's website or use a tool like the Mullvad Connection check.
DNS leaks can be a significant security concern, and the Mullvad Connection check can help identify them.
If you have a DNS leak, you'll see a red box with information about the leaking DNS servers, and you can contact Mullvad's support team for help.
You can also use the MaxMind website to look up the IP addresses and find out who they belong to.

Routers & Server Locations
We use anycast routing for our DNS servers, which means the nearest server should be used ideally. This is based on networking hops, not physical distance.
If one server is down, the next-closest server should be used. This ensures that you'll always have a working DNS server.
You can check which DNS server you're using by expanding the DNS box in our Connection check.

Routers
Routers can be a bit tricky to set up, but don't worry, I've got you covered.
If you've configured your router to connect to Mullvad VPN using WireGuard or OpenVPN, you might want to check out the Troubleshooting section of our router guides to fix any DNS leaks.
Asus Merlin and Mullvad VPN have a specific guide that can help you troubleshoot any issues.
WireGuard on a router running OpenWrt is another setup that can be prone to DNS leaks, but our guides can help you resolve the problem.
OpenWrt routers using OpenVPN with Mullvad VPN also require some extra troubleshooting to ensure a secure connection.

Server Locations
We use anycast routing, which means the nearest DNS server should ideally be used.
Anycast routing ensures that if one server is down, the next-closest server should be used.
This can differ between your ISP and their connectivity to our hosting providers, so the nearest server might not always be the same.
You can check which DNS server you are using by expanding the DNS box in our Connection check.
Wireguard
Wireguard is a popular VPN protocol that Mullvad uses to encrypt internet traffic. It's known for its high speeds and low latency.
Wireguard is a relatively new protocol, first released in 2016, and has gained a lot of traction since then. It's designed to be fast and lightweight, making it ideal for real-time applications like video conferencing and online gaming.
One of the key features of Wireguard is its ability to use UDP (User Datagram Protocol) for faster data transfer. This is in contrast to traditional VPN protocols like OpenVPN, which often use TCP (Transmission Control Protocol) for more reliability but slower speeds.
Wireguard is also highly secure, using end-to-end encryption and perfect forward secrecy to protect user data. This means that even if a hacker intercepts your traffic, they won't be able to decipher it without the encryption keys.
