DNS Leak Detection

Privacy Check DNS Analysis Security

This test checks if your DNS requests are being routed through your VPN's DNS servers or if they're leaking to your ISP's DNS.

Understanding DNS Leaks

A DNS leak occurs when your computer sends DNS requests outside of your encrypted VPN tunnel, revealing your browsing activity to your ISP. Even when connected to a VPN, DNS leaks can expose your real location and online activities.

What is DNS?

DNS (Domain Name System) translates domain names like google.com into IP addresses that computers use to communicate.

What Causes DNS Leaks?

DNS leaks can be caused by incorrect VPN configuration, Windows DNS settings, or applications that bypass your VPN connection.

How to Prevent DNS Leaks?

Use a VPN with DNS leak protection, enable "kill switch" features, and use secure DNS servers like those provided by your VPN service.
