Likely issued from AFRINIC-controlled inventory
No transfer record matches. AFRINIC's statistics show it reserved on 2020-02-28 and allocated (dated 2020-02-28) on 2020-02-29. The tracker saw this range released from hold on 2018-04-11 (41.217.248.0/21), 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 2018-04-11 and available on 2018-04-12. AFRINIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2013-12-16, 1577 days earlier. That is AFRINIC's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Removed from active registration. The tracker found it by comparing AFRINIC's daily statistics. AFRINIC's statistics show it allocated (dated 2009-07-14) on 2013-12-16 and reserved on 2013-12-17. 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.

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.
