Won't really solve anything - it will just move the question to "who is entitled to get an AS number?" and "do we really want to see 32 bit AS numbers?". We could always go for 128-bits! <running and ducking> :)
The problem with that isn't so much the lenght of the number (that's just "linear memory waste"), the problem that I see is that the number of ASes actually in use reflect the complexity of the overall topology - and *that* goes into BGP convergence times much stronger than linearily.
Seriously, what about the orginal problem? Is there any logical reason as to why not the Supernational-LIRs would not be allocated a block per sub-LIR?
I can speak only for myself here, of course. The way I see the current (new) policy, and the idea behind it, is to use *hierarchical aggregation*, which means "you get one big block and feed your sub-LIRs out of this". If you have a big block, say a /28, and each of your sub-LIRs gets a /32 out of it, and those that really need it announce the /32 to the world, the net impact on BGP is mostly the same, but for documentation purposes, it's still clear that "yes, this is all the same LIR". Not all of the /32s might even necessarily be visible globally, upstream could go through the /28. The new policy (effective next monday) will permit this - if you come up with good reasons and some thought about addressing plans and hierarchy, getting something "large enough" should not be a unsolveable problem. At least that was the intention - the address space is large enough so that haggling over "we need a /28" - "no you can only get a /31 plus a /32" should not occur (unless the "need" for a /28 really isn't justificable). Does this make sense to anybody?
