Enable DNS over HTTPS in Windows 11

WHAT IS DNS-over-HTTPS?
Microsoft has added a privacy feature to Windows 11 called DNS-over-HTTPS, allowing users to perform encrypted DNS lookups to bypass censorship and Internet activity.

DNS-over-HTTPS (DoH) allows your computer to perform these DNS lookups over an encrypted HTTPS connection rather than through normal plain text DNS lookups, which ISPs and governments can snoop on.

As some governments and ISPs block connections to sites by monitoring a user’s DNS traffic, DoH will allow users to bypass censorship, prevent spoofing attacks, and increase privacy as their DNS requests cannot be as easily monitored.

Chromium-based browsers, such as Google Chrome and Microsoft Edge, and Mozilla Firefox, have already added support for DoH. Still, it is only used in the browser and not by other applications running on the computer.

This is why it is helpful for an operating system to support the feature, as then all DNS lookups on the device will be encrypted.

YES, WINDOWS 11 IS GETTING THIS FEATURE!
Microsoft first released DNS-over-HTTPS to Windows Insiders for testing in Windows 10 preview build 20185, but they disabled it a few builds later.

With Windows 11, Microsoft has enabled the DoH feature again, and users can start testing it again if they are currently using DNS servers from Cloudflare, Google, or Quad9.

If the device is currently configured to use a Cloudflare, Google, or Quad9 DNS server, you can configure DNS-over-HTTPS using the following steps:
1. Open the Settings app.
2. Open the Network & internet page.
3. Click on the Properties button on the right.
4. On the next page, click the Edit button under DNS server assignment.
5. Select Manual from the drop-down list at the top of the page.
Specify the DNS server addresses that support DoH using the reference table below.
6. Select Encrypted only (DNS over HTTPS) from the in the Preferred DNS encryption and Alternate DNS encryption drop-down menus.
7. If your connection supports IPv6, repeat the previous steps for the its configuration.
8. Finally, click on the Save button.

That’s it. To check if the DoH feature actually works on your device, scroll down the contents of the Network & internet – Properties page. You should see “Encrypted” next to the DNS address value.

CHECKING THE DNS-OVER-HTTPS
Currently, Microsoft states that the following DNS servers are known to support DoH and can be used automatically by the Windows 11 DNS-over-HTTPS feature:
Cloudflare: 1.1.1.1 and 1.0.0.1 DNS servers
Google: 8.8.8.8 and 8.8.8.4 DNS servers
Quad9: 9.9.9.9 and 149.112.112.112 DNS servers

To see the configured DNS-over-HTTPS definitions already configured in Windows 11, you can use the following commands:
netsh dns show encryption
or
Get-DnsClientDohServerAddress

CAN I ENABLE THIS VIA THE GROUP POLICY EDITOR?
Microsoft has also added the ability to manage the Windows 11 DNS-over-HTTPS settings through group policies.

With Windows 11, Microsoft has introduced a ‘Configure DNS over HTTPS (DoH) name resolution’ policy under Computer Configuration – Administrative Templates – Network – DNS Client.

This policy allows you to configure the machine to use standard unencrypted DNS, prefer DoH, or require DoH.
