Hi Erik , Thank you for the comments.
Focusing on the second question as I already clarified the first one. The notification codes are designed so that the responder will always reply with the same values (that reflect its capabilities) and not as a function of the request. So, both codes will be returned together with the assigned address/prefix. If the initiator is still interested in the other AF, it has to follow: If a dual-stack initiator requests both an IPv6 prefix and an IPv4 address but receives an IPv6 prefix (or an IPv4 address) only with both IP4_ALLOWED and IP6_ALLOWED notification status types from the responder, the initiator MAY send a request for the other AF (i.e., IPv4 address (or IPv6 prefix)). In such case, the initiator MUST create a new IKE Security Association (SA) and request that another address family using the new IKE SA.
