The IP handling policy of WebRTC

This policy allows restricting which IP addresses and interfaces WebRTC uses when attempting to find the best available connection. See RFC 8828 section 5.2 (https://tools.ietf.org/html/rfc8828.html#section-5.2). When unset, defaults to using all available interfaces.

Example value: default

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
