About DNS Leak Test

The DNS Leak Test is a critical privacy tool for VPN users and security-conscious individuals. When you use a VPN, your DNS requests (the translation of domain names like 'google.com' to IP addresses) should effectively be handled by your VPN provider's secure servers. However, due to operating system misconfigurations or browser settings, these requests can sometimes 'leak' out to your ISP's default DNS servers, revealing your browsing history even when your VPN is active. This tool checks which DNS server is actually resolving your requests, helping you confirm that your identity remains masked.

How to Use DNS Leak Test

  • 1
    Connect to VPN

    Enable your VPN connection to the desired location before starting the test.

  • 2
    Run Test

    Click the 'Start New Test' button. The tool will query our secure endpoints.

  • 3
    Compare Locations

    Check if the 'DNS Server' location matches your VPN location. If it shows your actual ISP location, you have a leak.

  • 4
    Fix Leaks

    If a leak is found, check your VPN settings, disable WebRTC, or manually configure secure DNS servers.

Frequently Asked Questions

A DNS leak occurs when your computer accidentally uses your ISP's DNS servers instead of the anonymous ones provided by your VPN. This allows your ISP to see what websites you visit.
Most modern VPN apps have a 'DNS Leak Protection' setting you can enable. Alternatively, you can manually set your device's DNS to a secure provider like Cloudflare (1.1.1.1) or OpenDNS.
Yes. The test runs directly in your browser. We do not store your IP address or DNS query logs.
No. Incognito/Private mode only stops your browser from saving history locally. It does not hide your IP address or change how your computer routes DNS requests.
If you see 'Google LLC' or similar, it means you are using Google's Public DNS (8.8.8.8) instead of your ISP's servers. This is generally faster but means Google can see your lookups.
WebRTC is a browser feature for real-time video/voice. Sometimes it bypasses VPNs and reveals your real IP. A good VPN or browser extension can disable this vulnerability.
If you are using a VPN, this is good! It means your traffic is appearing to come from the VPN server's location. If you are NOT using a VPN, this could indicate a database error or that your ISP routes traffic through another region.
Yes. Mobile devices are just as susceptible. Some mobile VPN apps might not enforce DNS settings as strictly as desktop versions, especially when switching between Wi-Fi and cellular data.
