+1, there seems a problem to solve, so I support the adoption.

The question I would raise are:
* Do we want to add code and update IKEv2 or do we want to define an
extension with IP46_SUPPORTED. For interoperability, the latest may be
preferred.
* Looking at the code points, I have the impression that with the current
signaling, only the case where a single af is supported could be ambiguous.
A host sending a request for IP4 and IP6 addresses, can easily deduce is
which are the supported AF, except when the a single AF is supported. In
that case maybe the IP6 should be provided with the notification ,in case
the host really wants a IP4 address.
* While 3gpp use case is sufficient, I am wondering if we have use cases
outside 3gpp where such extension is needed ?

Of course these could be discussed after adoption.

Yours,
Daniel

&gt; Hi,<br>
&gt; <br>
&gt; after reading the draft&#39;s introduction, I think the problem described<br>
&gt; is real. So I support adoption of this draft.<br>
&gt; <br>
&gt; That said, it seems that the current draft solves the problem in <br>
&gt; suboptimal way (too many new notifications defined), but that<br>
&gt; can be definitely discussed in the WG. And yes, I&#39;m ready to <br>
&gt; review the draft.<br>
&gt; <br>
&gt; Regards,<br>
&gt; Valery.<br>
&gt; <br>
&gt;&gt; Our new charter has been approved and that includes item:<br>
&gt;&gt; <br>
&gt;&gt;      RFC7296 defines a generic notification code that is related to a<br>
&gt;&gt;      failure to handle an internal address failure. That code does not<br>
&gt;&gt;      explicitly allow an initiator to determine why a given address<br>
&gt;&gt;      family is not assigned, nor whether it should try using another<br>
&gt;&gt;      address family. The Working Group will specify a set of more<br>
&gt;&gt;      specific notification codes that will provide sufficient<br>
&gt;&gt;      information to the IKEv2 initiator about the encountered failure.<br>
&gt;&gt;      A possible starting pointing is<br>
&gt;&gt;      draft-boucadair-ipsecme-ipv6-ipv4-codes.<br>
&gt;&gt; <br>
&gt;&gt; So this email will start one week long WG adoptation call for that<br>
&gt;&gt; document [1] for WG adoptation.<br>
