We as an organization have to be careful to not be so ossified that we don't learn from our mistakes. In this case, the organization feels that we made a mistake (this is not an invitation to argue the point again, but a statement of facts as I see it). As a matter of procedure, the document we are talking about is the addressing architecture, which is now in its second round as a Proposed Standard. It might as well go through a third round if we haven't gotten it right (and then a fourth if necessary).


I am not suggesting at this time that IPv6 be completely torn up and started from scratch. What I am saying is that we have a working IPv4 Internet to fall back on when we find flaws in v6. Furthermore, let's not pretend that v6 is either so entrenched that we can make no changes or so fragile that we can make no changes.[*]

Fred's proposal, it seems to me, takes the WG consensus and starts to do the rational thing, which is to lay out usage scenarios that need to be addressed in the solution space. I think he does need to stay in the requirements space a bit more by allowing for the possibility of other than scoped addresses (and thus my one comment about the draft), but in general his approach seems to me to be correct.

Finally, let me make a comment about the appeal. I've been involved with working groups where they fragmented on different solutions and appeals were threatened and nasty names were used. The result were delays in implementation and deployment. Is that what you want? Or conversely, is it possible for you to take the consensus and build a working operating model with it?

[*] By the way, IPv4 didn't get to be so prevalent without a lot of pain and a lot of trial and error.
