Configure DNS over HTTPS (DoH)

DNS over HTTPS (DoH) is a technology for encrypting traffic to DNS servers that improves security, complicates resource blocking, and is also one of the tools for combating MITM. DoH is usually configured directly in the browser, but if an internet provider blocks communication over port 53 with third-party servers, using alternative DNS with DoH configuration in the browser will be insufficient, because many applications may also stop working correctly.

To configure DoH, set third-party DNS servers that support this technology, such as Google DNS or Cloudflare.

1. Open the browser settings:
2. In the "Privacy and security" section, go to "Security":
3. In the "Advanced" section, check "Use secure DNS", select "Use", and choose the appropriate DNS service:

1. Open the browser settings:
2. In the "General" section, under "Network Settings", click "Settings":
3. Enable "Enable DNS over HTTPS", select the appropriate DNS service, and click "OK":

1. Press Win+R, type regedit, and click "OK":
2. In the registry editor, go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters (you can copy this path and paste it into the address bar instead of the word Computer), right-click on an empty space in the right pane, select "New → DWORD (32-bit) Value", and enter the name EnableAutoDoh:
3. Double-click the parameter you created, enter 2 in the "Value" field, and click "OK":
4. Reboot the device to apply the changes to the DNS settings.
