Your DNS requests are a record of the websites you have visited. If they are not encrypted through a secure tunnel, they might be leaked and exposed to attackers and your ISP.
Prevent DNS leaks
What are DNS leaks and how do you prevent them?
When you visit a website, your browser sends out domain name system (DNS) requests to find the webpage you want. The DNS translates the domain names we use (like protonvpn.com) into IP addresses that computers use. If these DNS requests are not encrypted, your internet service provider can monitor your activity, along with anyone else. Proton VPN takes several steps to ensure your DNS requests are never exposed.
Your DNS requests are encrypted
Our VPN apps automatically encrypt your DNS requests and include them in the VPN tunnel, meaning they cannot be intercepted or read by any third parties in transit.
We run our own DNS servers
Proton VPN server has a DNS server that will resolve your DNS requests. No third party ever has access to them in an unencrypted state, including your ISP and DNS provider.
Test for DNS leaks
You can check that your VPN connection is secure by connecting to a server, going to a DNS leak test(new window) website, and running their standard or extended test. If the results show DNS servers that don’t belong to your actual ISP, your VPN connection is secure.
