While I do quite enjoy the occasional IPv6/IPv4 advocacy discussion, I would indeed prefer to keep *this* list a bit more focused on *address policy related* topics:
and we need policies for those that want some of the remaining IPv4 numbers.
The problem is that IPv4 address policy is affected a *LOT* by an answer to the following question:
When IPv6 will be really deployed?
Note that "never" can be a valid answer.
This question is something that we simply cannot answer - and even if we could, it doesn't matter. Some people do deploy IPv6 today (whether or not they "really" deploy IPv6 does not matter at all, as long as they need addresses for whatever they do), so we need IPv6 address policies to enable those to do so. Other people deploy IPv4 today, and will continue to do so, for a time frame unknown to me. So we also need IPv4 address policies. If the IPv4 pool runs out, we need to handle this, policy-wise. If it doesn't, because the Internet stops growing, everybody does NAT, or everybody migrats to IPv6, we don't - but we won't know in advance, so it is useful to have a plan for the case that it does run out. So - while the answer of your question might matter a lot to the well-being of the Internet at large, it has hardly any relevance on the policy work we do: "distribute numbers to those people that need numbers for their work, in an open, fair, and transparent way". (Note everybody agrees whether we do an optimum job here, and much of what we do turns out years later to be a "good" or "bad" decision, but that's the problem with todays crystal balls) Gert Doering -- APWG chair -- Total number of prefixes smaller than registry allocations: 128645 SpaceNet AG Vorstand: Sebastian v.
