What Is an IP Leak (and How to Prevent One)?
Even with a VPN, a leak can expose your real IP. Here's how to check and prevent it.
A VPN hides your IP — unless something leaks it. Here's what to watch for.
Common leak types
- DNS leak: your DNS requests bypass the tunnel, revealing sites to your ISP.
- WebRTC leak: a browser feature can expose your real IP even with a VPN on.
- IPv6 leak: IPv6 traffic slipping outside the tunnel.
How to check
While connected, run a leak test site. It should show only the VPN's IP and DNS — never your real ones.
How to prevent leaks
- Use a quality VPN that routes DNS through the tunnel. VPN Panda keeps your traffic inside the tunnel.
- Disable WebRTC in your browser if you're cautious.
