WebRTC leak test

WebRTC can reveal your real IP address to websites even while you're connected to a VPN. This test runs entirely in your browser — no data is sent to DXVPN — and tells you whether your browser is leaking.

Test takes about 5 seconds.

How this works: We open a local RTCPeerConnection with no STUN servers and collect its ICE candidates. A candidate is a possible network path the browser could use to reach a peer — and if any of them expose a public IP, that's a leak vector.

False positives: A .local hostname (mDNS) in candidates is normal in modern browsers and does NOT leak your real IP. Only candidates with numeric public IPs count as leaks. Virtual network adapters (Docker, VMware) may also surface private RFC-1918 IPs — those don't leak either.
