What is a WebRTC leak?

WebRTC (Web Real-Time Communication) is a browser technology for video calls that can accidentally expose your real IP address even when using a proxy or VPN. Our tool checks if WebRTC is leaking your local or public IP through STUN server negotiation.

How can I fix WebRTC leaks?

Install a WebRTC blocking extension like "WebRTC Control" for Chrome or disable WebRTC in Firefox via about:config. Some anti-detect browsers like Multilogin and GoLogin handle this automatically.

A DNS leak occurs when your browser sends DNS resolution requests through your local ISP instead of through the proxy, exposing your browsing history. Our tool provides a basic DNS leak assessment.

Is my proxy anonymous if this test passes?

If your IP shows as the proxy IP, no WebRTC leaks are detected, and your real ISP is hidden, your proxy is providing good anonymity. However, advanced fingerprinting techniques may still identify proxy usage.

Running STUN Check...

WebRTC (Web Real-Time Communication) is built into modern browsers like Chrome and Firefox to enable zero-plugin video calls. However, it can leak your real local or public IP address even if you are using a proxy or VPN. This test pings a STUN server to see what IP is returned.

DNS Leak Status

A DNS leak occurs if your network traffic routes through the proxy, but your DNS resolution routes through your local ISP, exposing your browsing history.

Standard Test OK

If your IP above matches your proxy node, basic browser-driven DNS resolution usually follows the same path in modern setups. (Advanced deeply-routed DNS leak testing requires external socket calls not available purely in browser JS).

Fixing WebRTC Leaks

If you saw an unexpected IP address in the WebRTC box, your identity is compromised. You can prevent this by installing extensions.
