What is a DNS query?
Whenever your device needs to connect to a server on the Internet, it needs to turn a domain name into a string of numbers called an IP address.
To do this, it sends a DNS request, usually to your Internet service provider (ISP), without you noticing.
Weaknesses of the DNS
The problem is that DNS queries can be censored by your ISP, either at the behest of the government or at its discretion.
Your ISP can also look at all your DNS queries to see which sites you visit and analyse your online behaviour and habits.
Circumventing censorship
With our DoH (DNS-over-HTTPS) service, you can encrypt your DNS queries to prevent your ISP from viewing or modifying them.
On our side, we receive your requests, decrypt them, resolve them ourselves and send you the answer to your request in encrypted form.
Easy to install
Once the service is installed, you don’t have anything else to do: your requests will be automatically processed by our service, no further configuration is required.
Our commitments
We do not apply any form of censorship to DNS requests.
We do not store the content of your requests: we limit ourselves to connection logs that we delete after 14 days.

We maintain this service for you
This service is maintained by La Contre-Voie, a non-profit association recognized of general interest. We ensure daily the proper functioning of this service.
However, we don’t have the financial resources of Google (we do not sell your data!) and if most of our services are free for you, they are not for us: their maintenance requires a personal and financial investment.
We cannot survive without your support. To help us, you can make a donation or join the association.
