No transfer record matches. LACNIC's statistics show it available on 2020-07-07 and allocated (dated 2020-07-08) on 2020-07-08. The tracker saw this range released from hold on 2020-07-07 (131.108.236.0/22), so it appears to have been issued again from LACNIC's pool. Another change to this range was reported the day before or after (2020-07-07: Released 131.108.236.0/22), 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 2020-07-06 and available on 2020-07-07. 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 (2020-07-08: Added 131.108.236.0/22), so the before-and-after statistics may include it.

Possible future reissue candidate after hold

Removed from active registration. The tracker found it by comparing LACNIC's daily statistics. LACNIC's statistics show it allocated (dated 2014-09-22) on 2017-07-26 and reserved on 2017-07-27. Public sources do not distinguish a voluntary return, revocation, or reclamation. LACNIC's current hold for IPv4 space applies to removals from 2020-03-01 on, and this one came earlier, so the tracker gives no estimate. This does not confirm availability.

No transfer record matches. LACNIC's statistics show it available on 2014-09-21 and allocated (dated 2014-09-22) on 2014-09-22. It moved from LACNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by LACNIC.

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.
