Can WebRTC Leak My Real IP Through a VPN?
WebRTC can expose network information to browser applications, which is why it is worth checking alongside a VPN. Modern browsers and VPNs often limit what is exposed, but the result should be interpreted carefully.
What WebRTC is doing
WebRTC enables real-time browser communication such as voice, video and peer-to-peer features. To establish connections, browsers can gather ICE candidates that describe possible network paths.
What counts as a concerning result
A useful check looks for an additional public IP address that differs from the public VPN address and appears to expose a connection you did not expect. Private local addresses or masked candidates are not the same thing as a public-IP leak.
What to do if you see an unexpected public IP
First confirm the VPN is connected, then rerun the test in a fresh browser session. Check whether your VPN application offers WebRTC or leak protection and whether browser extensions or unusual network settings are involved. Avoid assuming that every candidate displayed by a browser is your original public IP.
