Re: [rtcweb] IP handling: Using mDNS names for host candidates

One option could be that Mode 2 incorporates RFC 4941 stateless IPv6
addresses, if supported. Otherwise, mDNS is used. This mode would never
include RFC 1918 IPv4 addresses.

This would work well in more environments and still provide significant
privacy improvements.
