No transfer record matches. AFRINIC's statistics show it available on 2016-07-28 and allocated (dated 2016-07-28) on 2016-07-29. The tracker saw this range released from hold on 2016-05-30 (196.223.144.0/21), so it appears to have been issued again from AFRINIC's pool.

AFRINIC's statistics now list it as 'available'; reissue not confirmed
AFRINIC's statistics show it reserved on 2016-05-30 and available on 2016-05-31. AFRINIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2016-02-24, 96 days earlier. That is AFRINIC's own label: whether and when it is reissued is not confirmed.

Removed from active registration. The tracker found it by comparing AFRINIC's daily statistics. AFRINIC's statistics show it assigned (dated 2015-10-13) on 2016-02-24 and reserved on 2016-02-25. 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 reserved on 2015-10-13 and assigned (dated 2015-10-13) on 2015-10-14. The tracker saw it removed from registration on 2015-06-26 (109 days earlier), and it is back with the same holder record it had before, so it went back to its previous holder rather than to a new one: most likely a suspension lifted, a reinstatement or a correction.

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.
