<h2>WebRTC IP Leak VPN / Tor IP Test</h2>
|
|
|
|
<p>
|
|
WebRTC is a communication protocol that relies on JavaScript that can leak your actual IP address from behind your VPN. While software like NoScript prevents this, it's probably a good idea to block this protocol directly as well, just to be safe. This page will test if your internet browser is affected by the <strong>WebRTC Leak.</strong>
|
|
</p>
|
|
|
|
<p>
|
|
This demo secretly makes requests to STUN servers that can log your
|
|
request. These requests do not show up in developer consoles and
|
|
cannot be blocked by browser plugins like AdBlock, Ghostery, etc.
|
|
</p>
|
|
|
|
<p> </p>
|
|
<strong>Your local IP addresses:</strong>
|
|
<ul></ul>
|
|
<strong>Your public IP addresses:</strong>
|
|
<ul></ul>
|
|
|
|
<p> </p>
|
|
|
|
<p>Your browser is not safe and will show your real IP even though you are using a VPN service if you can see your real IP addresses here.</p>
