Yes, doubling does seem unwise. It would make sense (to me anyway) that once xx% of a /12 is allocated then another /12 is issued to the RIR.
Indeed. I see no point in unconditional doubling. I'm pretty confident that /12 blocks are large enough to serve a RIR long enough so that ordering a new /12 is not hampering anything. My suggestion would be to set aside a /8 per RIR (perhaps also a DNS reverse delegation for that) and allocate /12s to the RIRs upon their request. A RIR qualifies for a new /12 block as soon as nn% usage of the current /12 block is reached. nn might be 50% or more. As Randy suggests, the percentage should be low enough so that the RIRs can get new space without delaying allocation to LIRs (as it happens nowadays). Best regards, Daniel
