Removed from active registration. The tracker found it by comparing AFRINIC's daily statistics. AFRINIC's statistics show it allocated (dated 2013-05-21) on 2013-05-26 and not listed on 2013-05-27. Being gone from AFRINIC's statistics entirely can also mean it moved to another registry. Public sources do not distinguish a voluntary return, revocation, or reclamation. AFRINIC publishes no fixed period for which it holds returned IPv4 space before reissuing it, so the tracker gives no estimate. This does not confirm availability.

No transfer record matches. AFRINIC's statistics show it not listed on 2013-05-21 and allocated (dated 2013-05-21) on 2013-05-22. It wasn't in AFRINIC's statistics before, so it wasn't AFRINIC's unissued inventory; it may have come from another registry in a transfer not yet in the log.

RDAP lookups

Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
