False positive.

It reports "N/A" for my private IP address and still says "Your browser
is leaking webrtc ip-address!". My *public* IP address is not a secret,
when I visit a website.

Same - just showing my public address which is not a secret anyway.

Yes - especially those which offer video calls and live video streaming
using WebRTC. HLS ist not really suitable for video calls.

I did - both testsites above did *not* show my private IP address. And
no, I did not disable WebRTC.
