Excellent!
I'd like to state my guess that a good number to aim at might be about 1200 routes per fully-utilized class-A-sized chunk of address space. This would put the IPv4 end state at a maximum of about 250,000 routes, ... I like the idea of measuring each and every class-A-sized block against some standard separately, since a lot of the class-C space has been allocated to regional registries this way and it inconveniences those places which have done the best the least. I'm less attached to the number 1200 in particular, but I do think an explicit target should be chosen which represents both a tractable limit to design big routers for and which allows the implementation of efficient address allocation strategies which won't have to be tighened over time.
I suggest that it be 2048 for each _pair_ of class As, since that's how they were assigned in RFC-1366 & 1466. Bill.Simpson@um.cc.umich.edu Key fingerprint = 2E 07 23 03 C5 62 70 D3 59 B1 4F 5E 1D C2 C1 A2
