A proposed change to RIPE Documents ripe-589, "IPv6 Address Allocation and Assignment Policy", ripe-451, "IPv6 Address Space Policy For Internet Exchange Points" and ripe-233, "IPv6 Addresses for Internet Root Servers In The RIPE Region" is now available for discussion. [..] We encourage you to review this proposal and send your comments to <address-policy-wg@ripe.net> before 25 October 2013.
The discussion phase for this proposal is now over, but after the feedback received at the RIPE meeting in Athens (and here on the list, even if in the wrong thread :) ) the chairs have deviced to take a step back, and re-state the fundamental "do we want to go there?" question (and extend the discussion phase by +4 weeks). The proposal aims to unify IPv6 PA and IPv6 PI space into one kind of address space, "IPv6 addresses". This is the goal. The idea to go there came from various people in the community, mostly for one reason - having two differently "coloured" addresses that do the same thing, routingwise, but follow different policies and have different strings attached, creates quite some confusion for the folks out there that can no longer be nicely separated into "ISPs" (->become RIPE members, use PA) and "end-users" (->use PI, if BGP-based multihoming and/or upstream independence is required). Most notably, "garage style hosting providers" seem to have issues with the requirement of the IPv6 PI policy that PI space MUST NOT be sub-assigned, which the NCC interprets most strictly (because the vast amount of "grey" between "ok" and "not ok" is hard to codify into hostmaster guidelines). OTOH, I have not heard that complaint from actual hosting providers for a while, so maybe the issue is not that big anymore. *If* we go to "there is only one type of addresses" anymore, we have two options - abandon IPv6 PI (as in "not so expensive, but independent space") completely, problem solved -> I do not think we can reasonably do that - find a way to solve the needs for both RIPE members and non-members, with maximum flexibility, with only one type of addresses, taking "real world" address distribution chains (LIR->network operator-> hosting provider->customer->hosted virtual machines, for example) and "real world" financial constraints into account. 2013-06 aims to achieve the latter, while proposing / finding specific solutions for all the small details that come up if such a radical change is implemented. I think the presentation at RIPE67 was a bit too fast for the WG - it could have spent a bit more time on the background and "do we want to go there" before overwhelming you with questions about details to be solved. For that, I apologize - I did review the presentation beforehand with the proposers, and assumed "yes, this should work out nicely"... Anyway. I think what we need to hear now from the community (*you*) is where we want to go: - do nothing, our policy for IPv6 PA and IPv6 PI "as of today" is fine - keep the distinction, work on the IPv6 PI policy (if the pain is large enough that someone actually volunteers to come with a proposal) - go the big step, unify IPv6 PA and IPv6 PI, and solve all the detail problems that need to be addressed if we go there. Going for one of the first options would mean abandoning 2013-06 - but if that's what the community wants, it's much better to do it *now* than to invest more time in text, impact analysis, a few rounds of review phase, and *then* give up the project.
