DoH service

What is it?

DoH (DNS-over-HTTPS) is a new protocol that allows you to send DNS requests through HTTPS.

It has been designed to address long-standing issues around the confidentiality and integrity of DNS requests.

Since mass monitoring and the threat to net neutrality through the listening, interception or modification of DNS requests is no longer new today, we offer you this service that respects your privacy to regain control of your rights.

Find a Stéphane Bortzmeyer's lecture on DoH (French) for more detailed information on the subject.

Who is it for?

This service is free of charge for everyone.

Terms of service

By using this service, you unconditionally accept the legal notice and the Terms Of Service of our platform.

How does it work?

In its latest versions, Firefox still has this feature in beta-test.

To use it with our server, you must go to the Firefox preferences.

Open a new tab and write "about:preferences" in the address bar, then search for "dns".

Click on "Settings". Then, at the very bottom of the window, check "Enable DNS over HTTPS", then "Custom" and enter this: https://doh.42l.fr/dns-query (without slash at the end)

Now, test your settings by browsing a website and it should work :)

If you encounter any issues, do not hesitate to contact us.
