I have reviewed this document as part of the security directorate's
ongoing effort to review all IETF documents being processed by the
IESG.  These comments were written primarily for the benefit of the
security area directors.  Document editors and WG chairs should treat
these comments just like any other last call comments.

This documents adds Origin attribute to the STUN that can be used in
similar ways as the HTTP header field of the same name. The specified
use cases include logging, analytincs and to provide additional
information to the server in addition to the authentication
mechanisms used.

The draft notices that it can be set by attacker to any way, and can
be modified in transit, and that it can also have privacy
implications, so it should be protected using TLS or DTLS when needed.

I think this draft is Ready.
