Policies like giving each RIR one of the final five /8s were carefully created to give each RIR equal access to address space. Automatically giving legacy space to the RIR for the region that the holder of the legacy space is in is incompatible with that, and means that ARIN will get virtually all of it. To me, it seems both natural and fair that legacy space (especially /8s) is returned to IANA and then redistributed over the RIRs. By the way, IANA only deals in /8s. However, a lot of people got legacy /16s or other non-/8 sizes, so some /8s that are marked "legacy" actually contain a lot of unused space. Each of those /8 is "administered" by a RIR, but it's unclear (to me at least) whether that means that RIR gets to give out that space in its region or not. And if not, what is supposed to happen with this space. It's a significant amount, about half the size of the class E space: RIR Administerd by Delegated Free afrinic 33.55 M 8.71 M 24.85 M apnic 100.66 M 77.95 M 22.72 M arin 671.09 M 592.04 M 79.05 M ripencc 67.11 M 63.01 M 4.10 M
