Allocations of autonomous system numbers are made to regional Internet registries according to their needs,
based on allocation rates they publish. Specifically, RIRs are eligible for further allocations if their
available address space is 80% allocated, or the available pool does not satisfy two months of need based on
the previous six months' average allocation rate.
