Would be nice, but alas, it seems we're doomed to repeat most past mistakes. > Let each allocation be long > enough to contain sufficient address space; the space to the right is > reserved for growth. If I understand what you're suggesting, this is the rationale for the RIR's receiving /12s from the IANA. The theory was that the RIRs needed /12s in order for them to allocate address space via a bisection methodology, which would allow for growth in any of the allocations made. However, last I checked (which was a while ago), only APNIC had actually carried through on this -- all the other RIRs (if they were allocating out of the /12 blocks at all), were still allocating sequentially. Things might have changed (haven't been following what the RIRs do so closely anymore)...
