WebRTC IPs

A library to detect your local IP address via WebRTC on the web page.

Security notes

All modern browsers now require special flags to allow leaking local IP address.

Chrome:

Set enable-webrtc-hide-local-ips-with-mdns to disabled on chrome://flags page.

Or run chrome with arguments: --flag-switches-begin --disable-features=WebRtcHideLocalIpsWithMdns --flag-switches-end

Firefox:

Set media.peerconnection.ice.obfuscate_host_addresses to false on about:config page.

Safari:

Set Disable ICE Candidate Restrictions in Developer menu.
