Allocations of IPv6 address space 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 space of existing allocations is less than 50% of a /12 address block, or less than their necessary space for the following 9 months.
The chart below uses AFRINIC's current average allocation rate to forecast their available IPv6 space over the next 24 months. This can be used to estimate if AFRINIC will become eligible to apply for additional IPv6 space in the near future.

Number of IPv6 addresses allocated by AFRINIC to their network operators in the last six months.
IPv6 address blocks smaller than /32 are considered "fragmented". The chart below shows the number of fragmented blocks held by AFRINIC.
