-<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>&nbsp;</p>
-<strong>Your local IP addresses:</strong>
-<ul></ul>
-<strong>Your public IP addresses:</strong>
-<ul></ul>
-
-<p>&nbsp;</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>
