Which basically says that we should allow /48 prefixes punched from PA space in the Global Routing Table. I am sure the educated reader that subscribes to this list will appreciate, especially smaller LIRs that can't afford a c12416 or M160 to hold a huge routing table.
While I'm not sure whether it's "the perfect solution" (it isn't), I disagree with you on the "evilishness" of it. There are two dangers with it: - it might blow up the IPv6 table to the number of currently active IPv4 ASes. That would be about 15.000, and shouldn't hurt any decent router (yes, my 2503 will not like it, but then, I always knew that it's not a proper core router anymore). - if there really starts a big run to IPv6 multihoming, it will increase pressure on the AS allocation/conservation policy (and we'll eventually run out of 16 bit ASNs, which would hurt). Also, it might not even be sufficient - some companies might still want to be "really, really independent" and get their own address block. The *benefit* of "/48 multihoming" is that you can filter those routes if you don't want to see them - then your routers will send packets down the /32 road, and eventually hit a router that knows about the /48 (which is why I consider this approach superior to "everybody gets a independent prefix", which I can't properly aggregate). Which brings us back to "why I want ONE regional block per RIR" - that's why. (I do not think we need to discuss this - I won't be able to convince you, you won't be able to convince me - I just wanted to point out that there are more points of view to this) Gert Doering -- NetMaster -- Total number of prefixes smaller than registry allocations: 54837 (54495) SpaceNet AG Mail: netmaster@Space.Net Joseph-Dollinger-Bogen 14 Tel : +49-89-32356-0 80807 Muenchen Fax : +49-89-32356-299
