WebRTC leak test — does your browser expose your real IP | vpn.how
Free WebRTC leak test: check whether your browser exposes your real IP address, bypassing your VPN. Runs entirely in your browser.

WebRTC leak test

WebRTC is the browser technology behind video calls and P2P. It can expose your real IP address even with a VPN on, bypassing the tunnel. This test shows which IP addresses your browser reveals via WebRTC right now.

Testing WebRTC…

A VPN hides your IP — if it hides all of it

A WebRTC leak reveals your real address even when you think you are hidden. A personal vpn.how server routes all traffic through the tunnel, and a dedicated clean IP stays off blocklists — no neighbours, no leaks.

Frequently asked questions

What is a WebRTC leak?

WebRTC is a browser technology for video calls and P2P connections. To connect, the browser requests your IP addresses directly — and may reveal your real public IP even with a VPN on, bypassing the tunnel.

Why is a WebRTC leak dangerous?

A website or service can learn your real IP and location even though you believe you are hidden behind a VPN. It defeats the privacy purpose of using a VPN.

How do I protect against WebRTC leaks?

Disable WebRTC in your browser or via an extension — or use a VPN that routes all traffic through the tunnel. On a personal VPN server you fully control routing, so WebRTC shows the server IP, not your real one.

If the test found nothing, am I safe?

Most likely yes: the browser did not expose a public IP via WebRTC. Modern browsers mask local addresses (mDNS). But re-run the test with your VPN on — what matters is that your real public IP is not exposed while connected.
