Hi,

According my experiences WebRTC implementations don't send any
REQUESTED-ADDRESS-FAMILY STUN/TURN attribute.
https://tools.ietf.org/html/rfc6156#section-4.1.1

If the REQUESTED-ADDRESS-FAMILY attribute is absent, the server MUST
allocate an IPv4-relayed transport address for the TURN client.

This way TURN servers will allocate IPv4 address even if the Allocation
request sent on IPv6 connection to the TURN server.

I think this may cause confusion in developers and so we should make it
configurable in WebRTC API.
Do you aware of this?
What is your opinion?

Thanks,
Misi
