Just to clarify the meaning of " Current /32 allocations from the /12 block can grow up to /24 at this stage". Based on the sparse allocation mechanism, the more allocations we make in the pool, the smaller size each allocation can grow. At this stage, every allocation can still have a room grow up to /24. In the future, more and more allocations add to the pool, the maximum growth size for each allocation will be reduced. It is possible reduce to /25, /26/ etc. Cheers, Guangliang ========= > APNIC has been using spare allocation method to make IPv6 allocations from the /12 block since we received it from IANA. We don't do reservation in sparse allocation, but in fact every allocation has a room to grow. Thanks for confirming. > Current /32 allocations from the /12 block can grow up to /24 at this stage. Err. That suggests APNIC is not using sparse (aka bisection) allocation, rather APNIC now just reserves the the /24 instead of the /29...?
