Framed-IPv6-Address AVP ( 168 )

This attribute indicates an IPv6 address that is assigned to the NAS-facing interface of the RG/host. It MAY be used in Access-Accept packets and MAY appear multiple times. It MAY be used in an Access-Request packet as a hint by the NAS to the RADIUS server that it would prefer this IPv6 address, but the RADIUS server is not required to honor the hint.
