Why Test Your VPN for Leaks?
A VPN is only as strong as its leak protection. Regular checks confirm your IP, DNS, and browser signals stay private even when networks change.
Types of VPN Leaks
- IP leaks: Your real IP becomes visible despite the tunnel.
- DNS leaks: DNS requests bypass the VPN resolver.
- WebRTC leaks: Browser APIs reveal local IP addresses.
- IPv6 leaks: IPv6 traffic bypasses an IPv4-only tunnel.
How Our Test Works
The test runs multiple checks in parallel to validate privacy coverage.
- Compare your public IP with the VPN endpoint.
- Inspect DNS resolvers for off-tunnel requests.
- Audit WebRTC discovery signals and browser routes.
- Validate IPv4 and IPv6 connectivity paths.
Common VPN Issues and Solutions
DNS leaks
Cause: the system resolver bypasses VPN DNS. Fix: enable DNS leak protection in your VPN app.
WebRTC exposure
Cause: browser APIs leak local IPs. Fix: disable WebRTC or use a privacy extension.
Kill switch gaps
Cause: brief disconnects expose your real IP. Fix: enable and test the VPN kill switch.
IPv6 bypass
Cause: VPN only routes IPv4 traffic. Fix: disable IPv6 or use an IPv6-capable VPN.
Privacy Note
All tests run in your browser and we do not store results or IP details. Run a check after VPN updates or when switching networks for best coverage.
