Geza,
I do see it differently. PI address space is easy to use, however, this allocation mechanism does not scale. Therefore was invented CIDR and PA allocation, if you do remember...
Could you eleborate on "does not scale" ? When deploying IPv6 one should set aside an IPv4 mindset. The same goes for the whole rehashing of the "does not scale" issue. You can't expect early 90's routing hardware to do the job of current BGP Internet routing. And when everyone will be running IPv6 (not tomorrow), the current limits for hardware won't apply. Let's not go into a discussion on asics / 64-core cpu's, but I'm pretty certain that hardware including tcams etc will keep up if the market demands it. Maybe you're referring to something altogether different, that's why I ask. I fully concur with Thomas on this point: for all the IPv4 PI allocations out there it should be possible to get an IPv6 allocation as well. Indeed nothing has changed with regard to the reasons for applying and being granted PI space. The current policy kind of suggests that everyone with IPv4 PI space should just quit their business and hand it over to the LIR as they are the only ones getting PI space for customer traffic. Regards, Albert

Nothing stops anybody of using PA, neither in IPv4 nor in v6. That's not the question.
But any reasons, why somebody wants/needs IPv4 PI space will usually fully apply to IPv6 also. It would seem stupid to me, to have IPv4 ("the past") as PI but IPv6 ("the future") as PA. That won't make sense. What changed between my v4 PI application and my v6 PI application? If I won't need PI on v6 any more, I probably won't need it on v4 any longer.
Siple question: do I need my machines to have provider independend IP addresses or not? If yes, then I need *ANY* address (IPv4, IPv6, IPvSomething) to be PI and not PA.
So, if somebody already has IPv4 PI space, he/she should more or less automatically receive v6 PI under the same conditions as for v4. He/she just has to reason, why some default /48 won't be enough. Thats my opinion.
regards, Thomas
