Looking for an IPv6 naysayer...

My claim is that about the time these zones are rolling out, the registrants currently using v4 provisioned hosting services and end users currently using v4 provisioned eyeball networks will also, at least in some cases, be using dual stack and/or v6 services.

You do not have to abandon v4 to deploy v6. That's an absurd claim.

Again, the need for v6 is not predicated on the abandonment of v4.

> where the v6 ab initio convinces me some is the area i currently work on -- developing economies. nigeria is a good example, fewer than 10^^5 computers, a population of 15x10^^7, and cell phone penetration rate approaching 1 in 3. even so, the number of v6 prefixes in afnic's inventory of allocations is ... very small ... for all of africa as a region.
I believe AfriNIC has a /12 like any other RIR. I'm not sure what you are saying here.

I'm not sure what you mean by _sparce_.

My claim is that by 4q2012, I expect we will see much much wider IPv6 deployment and potentially eyeball
networks that are primarily or exclusively IPv6 with at best limited or degraded IPv4 support through multiple
layers of NAT.

As such, I think that registries spinning up in 3q2012 should be required to have IPv6 support. yes.

> if your claim is that v6 is mandatory to implement sometime soon, i'm fine with that rather flexible temporal requirement, but icann's current rules of the road are an application that isn't v6 ready at transition to delegation (roughly two years from now) fails.
If you define soon as prior to 2q2012, then, yes, I'm fine with that. However, that seems to be about a quarter
earlier than you think these things will be starting up. Since you seem to be claiming they should get some
period beyond that where they don't need to run IPv6 (I'm not sure where they're supposed to get their
addresses to run on IPv4 by then, frankly), I think your definition of soon and mine are probably not

I don't think that 1q2012 is especially out of line given a 2q2012 target date.

I think it is irresponsible at this point to consider deploying any major network infrastructure without requiring IPv6 capabilities at deployment. IANA is already out of IPv4. If you expect these systems to start getting deployed in 3q2012, then, you're talking about a time which is likely to be well past RIR exhaustion in most cases. I suppose they can get a /22 from APNIC, but, other than that, where do you expect these organizations to even get IPv4 to work with?

Any time.
