🔍 DNS Leak Test & VPN Checker - Free Privacy Tool

A DNS leak occurs when your DNS queries (requests to resolve domain names) bypass your VPN or proxy, revealing your real IP address and location to your ISP or third parties. This compromises your privacy, even if you're using a VPN.

Common causes include misconfigured VPNs, IPv6 issues, or browser settings—testing regularly is key to staying protected.

Testing for DNS leaks ensures your VPN is working correctly and not exposing your true location or browsing activity. It's essential for privacy enthusiasts, journalists, or anyone in restricted regions.

If a leak is detected, you could be tracked—use our tool to verify and fix issues before they become problems.

Our DNS leak test sends queries to multiple DNS servers and checks if they route through your VPN or reveal your real IP. It analyzes responses for leaks, showing details like server locations and IP addresses.

Results are instant and private—no data is stored, making it safe for repeated tests.

To fix a DNS leak:

• Switch to a reliable VPN with built-in leak protection (e.g., kill switch).
• Disable IPv6 in your VPN settings or OS.
• Use DNS servers provided by your VPN (e.g., 8.8.8.8 for Google, but prefer encrypted ones like DNS over HTTPS).
• Clear your DNS cache and retest.

Retest with our tool after changes to confirm the fix.
