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
