Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it available on 2019-04-25 and allocated (dated 2019-04-26) on 2019-04-26. It moved from LACNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by LACNIC. Another change to this range was reported the day before or after (2019-04-25: Released 192.92.154.0/24), so the before-and-after statistics may include it.

LACNIC's statistics now list it as 'available'; reissue not confirmed
LACNIC's statistics show it reserved on 2019-04-24 and available on 2019-04-25. LACNIC moved it from its reserved (held) records to the status it calls 'available'. That is LACNIC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2019-04-26: Added 192.92.154.0/24), so the before-and-after statistics may include it.

The RIPE NCC's statistics show it reserved on 2014-04-17 and available on 2014-04-18. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2012-10-05, 560 days earlier. That is the RIPE NCC'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 the RIPE NCC's daily statistics. The RIPE NCC's statistics show it assigned (dated 1992-08-25) on 2012-10-04 and reserved on 2012-10-05. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC's current hold for IPv4 space applies to removals from 2014-03-26 on, and this one came earlier, 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.
