Check whether your browser's WebRTC connection exposes IP addresses. Run a free real-time WebRTC leak test without installing software.
Check what IP information your browser exposes through WebRTC.
Only information exposed by your browser is displayed.
A WebRTC leak test checks whether your web browser exposes network IP addresses through WebRTC connection candidates. This can be useful when testing browser privacy, VPN configurations and network security.
Our free WebRTC Leak Test uses the browser's WebRTC APIs to inspect ICE candidates generated by your browser. It does not invent or randomly generate IP addresses.
WebRTC is a browser technology used for real-time communication, including video calls, audio calls and peer-to-peer connections. During connection establishment, browsers can generate ICE candidates containing network information.
Depending on the browser, operating system, network configuration and privacy settings, some IP information may be exposed through these candidates.
WebRTC behavior varies between browsers and configurations. Modern browsers may use mDNS hostnames to protect local IP addresses, while public or server-reflexive candidates may still contain network information.
A WebRTC test therefore reports what your current browser actually exposes instead of assuming that a leak exists.
If you are using a VPN, you can run this test before and after connecting to the VPN. Compare the detected candidates to determine whether your browser is exposing unexpected network information.
If the test shows an unexpected IP address while you are using a VPN, check your VPN provider's WebRTC protection settings and browser privacy configuration. Browser extensions may also change WebRTC behavior, but extensions should only be installed from trusted sources.
Modern browsers can use mDNS hostnames instead of directly exposing local IP addresses in WebRTC candidates. An mDNS candidate is not the same thing as displaying your local IPv4 address.
You can run this test on supported mobile browsers. WebRTC support and privacy behavior can vary between browsers and operating systems, so results may differ between devices.
This tool performs the WebRTC check inside your browser. Detected candidate information is displayed on the page and is not intentionally sent to a third-party IP database for identification.
A WebRTC leak test checks IP information exposed through WebRTC ICE candidates generated by your browser.
Yes. The tool is free to use online.
It displays IP addresses that your browser actually exposes through WebRTC candidates. It does not generate fake IP addresses.
A VPN can change the network path, but WebRTC behavior depends on the browser, VPN configuration and network environment. The best way to check is to test the browser while the VPN is connected.
An mDNS candidate is a hostname used by supported browsers to avoid directly exposing certain local IP addresses through WebRTC.
Your browser may be using privacy protections, mDNS, restricted WebRTC settings or another configuration that prevents directly exposing an IP address.
No. WebRTC does not automatically mean that an IP leak exists. The result depends on the browser and current network configuration.
Yes, if the browser supports the required WebRTC APIs. Results can vary between mobile browsers.
No. The test runs directly in the browser and does not require software installation.
No. The tool reports candidates generated by the browser's WebRTC API.
