What is a WebRTC leak?

WebRTC can expose your real IP address even when using a VPN, because WebRTC makes direct peer connections that bypass the VPN tunnel.

How do I fix a WebRTC leak?

Disable WebRTC in your browser settings or use a VPN that blocks WebRTC leaks. Brave browser blocks WebRTC leaks by default.

Does this test actually leak my IP?

No — this is a read-only test. We detect and display your IPs but do not store or transmit them anywhere.

🌐 What is WebRTC?

WebRTC (Web Real-Time Communication) is a browser API for peer-to-peer video, audio and data. It uses STUN servers to discover your real IP — bypassing proxies and VPNs.

🔓 Why is it a privacy risk?

Even with a VPN active, WebRTC can expose your real public IP and local network IPs (192.168.x.x, 10.x.x.x) to any website that requests them via JavaScript — no permissions needed.

🛡️ Am I affected?

All major browsers (Chrome, Firefox, Edge, Safari) support WebRTC. If you use a VPN for privacy and your VPN doesn't block WebRTC, websites can see your real IP address.

✅ How to fix it

Disable WebRTC in your browser settings, use a browser extension like uBlock Origin (with WebRTC blocking enabled), or use a VPN that has built-in WebRTC leak protection.

How to Fix a WebRTC Leak

Chrome / Edge

Install the "WebRTC Network Limiter" extension from the Chrome Web Store, or go to chrome://flags and disable WebRTC for complete blocking. Better: enable uBlock Origin's WebRTC blocking in its settings.

Firefox

Type about:config in the address bar → search for media.peerconnection.enabled → set it to false. This completely disables WebRTC in Firefox.

Brave Browser

Go to Settings → Privacy and Security → WebRTC IP Handling Policy → select "Disable Non-Proxied UDP". Brave has built-in WebRTC protection.

Use a VPN with leak protection

ProtonVPN, Mullvad and ExpressVPN all have built-in WebRTC leak protection. Always check with this tool after connecting to confirm protection is working.

Frequently Asked Questions

Does a VPN protect against WebRTC leaks?

Not automatically. Most VPNs route your regular traffic through an encrypted tunnel but do not block WebRTC requests. Check your VPN provider's documentation for WebRTC leak protection, or verify with this test tool while your VPN is active.

What are local IP addresses?

Local IPs (like 192.168.x.x or 10.x.x.x) are your network addresses assigned by your router. WebRTC can expose these alongside your public IP, revealing that you're on a home network, office network, or VPN subnet.

Is WebRTC dangerous to keep enabled?

WebRTC itself is not malicious — it enables useful features like video calls. The risk is specifically the IP exposure. If you need WebRTC for services like Google Meet or Zoom, use a VPN with leak protection rather than disabling WebRTC entirely.

Why does the test show multiple IPs?

WebRTC gathers all available network interfaces: your VPN IP, your real public IP, your local/private IPs, and IPv6 addresses. Multiple IPs being shown is not automatically a leak — a leak occurs when your real public IP differs from your VPN IP.

How accurate is this test?

This test uses the same STUN-based technique that websites use to detect IPs. It is accurate for detecting standard WebRTC leaks. Some browsers or extensions may block STUN requests entirely, resulting in no IPs being detected — that is a safe result.
