Well, this is an interesting way of looking at things. Since IPv4 has been routinely NATted for most users for most of the time since broadband arrived, it had never occurred to me before this morning that some people interpret "dual stack" to mean no NAT44. RFC 4213 is agnostic about NAT afaik. It does assume that the ISP has a supply of IPv4 addresses, but it doesn't assume they are globally routeable. Also, its language doesn't say that it's *the* solution: The mechanisms defined here are intended to be the core of a "transition toolbox" -- a growing collection of techniques that implementations and users may employ to ease the transition. The tools may be used as needed. Implementations and sites decide which techniques are appropriate to their specific needs. When I mentioned operators (including my home ISP) that happily operate dual stack, I was certainly assuming CPE NAT, and operators that have enough IPv4 space for one-address-per-customer. Clearly operators that aren't in that position will make a different trade-off. That's been driving a great deal of work in the last few years: CGN for NAT444, 100.64.0.0/10, NAT64/DNS64, DS Lite, XLAT and more. I just don't see the point in defining some sort of "official" position of the IETF. Who does that help? Brian
