Likely issued from AFRINIC-controlled inventory
No transfer record matches. AFRINIC's statistics show it reserved on 2020-01-24 and assigned (dated 2020-01-23) on 2020-01-25. The tracker saw this range removed from registration on 2019-11-18 (192.231.237.0/24), so it appears to have been issued again from AFRINIC's pool.

Removed from active registration. The tracker found it by comparing AFRINIC's daily statistics. AFRINIC's statistics show it assigned (dated 2019-07-18) on 2019-11-18 and available on 2019-11-19. 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.

The tracker saw it removed from registration on 2017-04-14 (825 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.
