VPN Security Tester
Comprehensive security check for your VPN connection. We test for IP leaks, DNS leaks, WebRTC exposure, and IPv6 vulnerabilities to ensure your privacy is protected.

Understanding VPN Leaks
What is a DNS Leak?
When you use a VPN, your DNS requests (translating website names to IPs) should go through the VPN tunnel. If they bypass the tunnel and go to your ISP's DNS servers, your ISP can see every website you visit. This is a "DNS leak".
What is a WebRTC Leak?
WebRTC is a browser feature for real-time communication (like video chat). It can sometimes reveal your real IP address even when using a VPN. A good VPN should block these requests or ensure they use the VPN IP.
IPv6 Vulnerabilities
Many VPNs only tunnel IPv4 traffic. If your ISP provides an IPv6 address and your VPN doesn't handle it, traffic may leak over the unsecured IPv6 connection, revealing your identity.
