Step 1: Use a Reliable VPN

The most effective way to prevent DNS leaks is to use a VPN with built-in DNS leak protection. Premium VPNs like NordVPN route all your DNS queries through their own encrypted servers, ensuring nothing leaks to your ISP.

Step 2: Enable DNS Leak Protection

Most quality VPNs have a "DNS leak protection" toggle in their settings. Make sure it's enabled. This forces all DNS requests through the VPN tunnel.

Step 3: Change Your DNS Servers

If you can't use a VPN, switch to a privacy-focused DNS provider:

Step 4: Disable WebRTC

WebRTC can leak your real IP even with a VPN. In Firefox, go to about:config and set media.peerconnection.enabled to false. For Chrome, use a WebRTC blocking extension.

Step 5: Test Again

After making changes, run our DNS Leak Checker again to confirm your connection is now secure.

Stop leaks for good

A VPN with private DNS on every server, a kill switch and WebRTC protection closes every leak this site tests for.
