We'll have to see another knee in route proliferation before this becomes a problem, and space exhaust would most certainly prevent this from happening.
Ah, but with what minimum prefix length: a) Verio-esque b) /24 - current 'global minimum filter length' c) /32 d) A mixture between (a) and (b) - current situation People need to recognize that there is defacto filtering going on out there is everyone's network (well, nearly everyone's), in that very few people accept longer routes than a /24. In a CIDR world that's a different filtering rule to the Verio one, but it's still arbitrary (in some senses - think non-RIR assigned class A space - rather more arbitrary). IE is the assumption space exhaust will precede the problems you predict on router hardware precisely BECAUSE RIR allocation rules (the more sensible ones), and the /various/ filtering, dampening policies and the othr pro-aggregation work, has determined a minimum useful prefix size? In which case getting rid of the policies which make your assumption correct would be a bad thing. -- Alex Bligh Personal Capacity.
