What WebRTC can expose
WebRTC is a browser technology used for real-time communication. During connection discovery, a browser can expose network candidates. Modern browsers may show private addresses or masked mDNS candidates, which are not the same as exposing an additional public IP.
What NetPrivacyScan looks for
The test focuses on whether WebRTC reveals a public IP beyond the connection already visible to the site. This avoids alarming users simply because WebRTC candidates exist.
No public IP leak detected means the test did not find an additional public IP in the WebRTC candidates it could observe.
If you see an unexpected public IP
Confirm that your VPN is connected, reload the browser, and test again. Browser extensions, VPN configuration and browser privacy settings can affect WebRTC behavior.
