The check found a WebRTC leak. How do I stop it?

Use a VPN or browser that blocks WebRTC IP discovery, or install a WebRTC-limiting extension. In Firefox you can set media.peerconnection.enabled to false — but calls will stop working.

Is a local IP (192.168.x.x) leak dangerous?

It reveals little on its own — most home networks share those ranges. The concern is your public IP showing while you're on a VPN, which defeats the VPN's purpose.

Should I disable WebRTC entirely?

Only if you never make browser calls. Disabling it breaks video meetings in the browser; a leak-blocking VPN or extension is the more practical fix.

Why WebRTC matters for both calls and privacy

WebRTC powers browser video calls — Meet, Teams, Zoom's web client. The same machinery can expose your real IP address even behind a VPN, which is the "WebRTC leak" the second panel probes for using only your own browser.
