This would surprise me, since if it were true, then every phone would need
to be provisioned with a RADIUS shared secret, which I doubt.  The
NAS-IPv6-Address attribute is meant to be sent from server to client,
not the other way around, so IPv6 addresses can't be assigned that
way. There are Framed-Interface-Id and Framed-IPv6-Prefix attributes, but
those are meant to be consumed by a NAS in order to inform its PPP
Link-Identifier negotation and RA, respectively.

Sounds like we are witnessing the "immaculate configuration"!
