How to enable DNS-over-HTTPS (DoH) in Windows 10

DNS-over-HTTPS (DoH) allows DNS resolution to be performed over the HTTPS protocol.

ISPs tend to block your connection to websites by monitoring DNS traffic. With DoH (DNS-over-HTTPS), you will be able to improve the security of your connection and increase the privacy of your network.

For example, if you're connected to public WiFi, you can use DoH to prevent other users on the same network from seeing what websites you visit. Additionally, this could also prevent potential spoofing or phishing.

How to enable DoH support in Windows 10

DoH support is included in preview builds of Windows 10, but the feature is not enabled by default. If you want to use DoH when making DNS queries in your apps or browsers, you can enable it manually from Settings or by modifying the Windows Registry.

First of all, make sure you're on the Dev Channel of the Windows Insider program and have upgraded to Build 19628 or later.

To enable DoH in Windows 10, follow these steps:

• For Ethernet (wired) connections, open Settings > Network & Internet > Status.
• Click Properties and choose Edit IP or Edit DNS.
• On Wi-Fi (wireless) connections, open the network page and click the adapter properties link, then select Edit IP or Edit DNS.

"Once encryption is enabled, you can confirm that it is working by looking at the applied DNS servers in the properties and seeing them marked as '(Encrypted)' servers," Microsoft noted in a blog post published earlier this year.

This feature is expected to be released later this year or next year.

Enabling DoH in Google Chrome

Chrome 83 – and later versions – supports DNS-over-HTTPS, but the feature is not enabled by default for all users.

To enable DoH in Google Chrome, follow these steps:

1. Go to Settings.
2. Open the Privacy and security section.
3. Look for the Use Secure DNS setting.
4. Enable it and use your current service provider or alternative DNS providers, such as Cloudflare and Google.

If you don't see the above setting, it means that DoH support has not yet been released to your installation . You can still enable it using a test flag by following these steps:

1. Type “chrome://flags/#dns-over-https” in Chrome’s address bar.
2. Click the “Default” drop-down menu.
3. Select “Enabled”.
4. Restart Chrome.

Enable DoH in Microsoft Edge

After Google Chrome, Microsoft Edge also gains support for DoH.

To use the feature, download and install the Microsoft Edge Dev build and follow these steps:

1. Open Edge settings.
2. Go to the “Privacy, search, and services” tab.
3. In the “Security” section, locate the option “Use secure DNS to specify how to lookup the network address for websites”.
4. Enable it and use your current service provider or alternative DNS providers, such as Cloudflare and Google.

Enable DoH in Firefox

To enable DoH in Firefox, follow these steps:

1. Open Firefox settings.
2. Search for “DoH” in Settings and select change network.
3. In the “Connection Settings” window, enable DNS over HTTP and select the DNS provider.
