Talk of IPv6 space hoarding and fragmentation. Ughh. Perhaps we can avoid repeating IPv4 mistakes with IPv6.
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)... Regards, -drc
