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 2019-10-07 (154.66.116.0/22), 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 2019-10-07 and available on 2019-10-08. AFRINIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2018-03-07, 579 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 2013-10-24) on 2018-03-07 and reserved on 2018-03-08. 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 available on 2013-10-24 and allocated (dated 2013-10-24) on 2013-10-25. It moved from AFRINIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by AFRINIC.

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.
