DoH service

D'oh !

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.

Technical information

Conceive that we don't have the speed of Google or Cloudflare.

It is a DoH proxy. We take your DNS requests from HTTPS and perform them ourselves over the DNS protocol on the following resolvers:

Those resolvers are maintained by associative French Internet Service Providers, members of the FDN Federation, commiting for net neutrality.

We keep access logs for this service (date and time, IP, browser) in accordance with our legal notice, but we do not store the content of your requests.

DNSSEC is enabled on our domain.

For more information, you can consult our technical report.

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".

Firefox settings

Click on "Settings". Then, at the very bottom of the window, check "Enable DNS over HTTPS", then "Custom" and enter this: (without slash at the end)

Firefox settings: DNS

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

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