> One other point regarding Ole's comments below - Ole, I don't think it would be possible to handle IPv4 configuration by just adding a DHCPv6 DHCPv4 container option to encode the various v4 options as some of the information is conveyed in non-option fields in the DHCPv4 (BOOTP) packet. Yes, you could have an option that has those fixed fields followed by a variable length option encoding area, but that seems much more complex than just encoding the DHCPv4 packet (as we are proposing to do with the new DHCPv6 messages). Also, encoding as an option of options would also require piggybacking the request with DHCPv6 requests themselves which has other implications -- so I think that design, while possible, is much less optimum (though we can certainly disagree on this point).

just to make it clear; I do not in any way want to give the impression that I'm in favour of this mode. I'm not.

cheers,
Ole
