On 3 April 2017, AFRINIC's available pool of IPv4 address space reached a point where we have to start allocating or assigning addresses from the"final /8" (pronounced "slash eight"). This triggered Exhaustion Phase 1 as defined in the IPv4 Soft Landing policy, which appears in section 5.4 of the Consolidated Policy Manual. Accordingly, the requirements for AFRINIC to allocate or assign IPv4 address space have changed.
This is an event that has been anticipated for many years. A policy was created about six years ago to define what would happen when AFRINIC reached this milestone. The other four Regional Internet Registries (RIRs) all passed equivalent milestones a few years ago.
