Hi Eric, |1) PI in IPv4 is currently complex due to the many pre-CIDR |deployments. |I can't remember how many Class Cs and Class Bs we had before we traded |many of them in but it was probably triple digits. Certainly we all |recognize that pre-CIDR allocations harm aggregation. Regardless, PI in |IPv6 must always be treated in a CIDR-like manner so it should have |better aggregation characteristics than IPv4.
Just FYI, all v6 allocation right now is being done in a PI manner. |4) The large end user, particularly governments, obviously |need PI space |for the reasons I've discussed far too much recently. s/need/want/. I have yet to see any site that could not suffice with PA space. Yes, it would have some (possibly painful) impact, but it is doable. |5) Therefore, the issue that concerns you probably centers upon how the |many medium sized corporations and entities will be supported. |I suggest |that network requests above a certain size may qualify for PI and must |be handled by an entity other than ISPs, to counteract the issue you |observed above. ISPs should only be able to allocate from their own PA |space. My issue is simple, and is still the one I initially raised: can we reasonably recommend an architecture that requires renumbering (either once, or repeatedly)? Your answer is a clear and resounding 'no', coupled with a preference for NAT based soliutions.. |My recommendation, therefore, is that your issue, Tony, be handled by |only enabling ISPs to hand out PA addresses for their own |customers only |and have some other worldwide administrative entity be responsible for |allocating PI addresses for the Internet. There should be a well-known |cost for "buying" certain PI CIDR address range sizes from that entity |for private use (i.e., address ownership should cost something). That |latter administrative entity needs to be guided by well-established |policies so that their actions will be consistent, fair, and above |reproach with a well-known mechanism established for review |and handling |disputes. They need to be particularly sensitive to requests |coming from |governments. In short, it's a non-technical issue with only a socio-economic solution. That's not very satisfying from an architectural issue. Just as there is clear over-use of PI space today, there is no technical basis here for requiring certain 'have-not' end-users to remain with local prefixes while the 'haves' get global PI service.
