Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it reserved on 2018-08-12 and allocated (dated 2018-08-13) on 2018-08-13. It moved from LACNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by LACNIC.

LACNIC's statistics show it reserved on 2018-07-20 and available on 2018-07-21. 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.

Possible future reissue candidate after hold
Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 2010-01-05) on 2010-12-21 and not listed on 2010-12-22. Being gone from APNIC's statistics entirely can also mean it moved to another registry. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, and its statistics show a steady one (a year) only for removals from 2014-07-01 on; this one came earlier, so the tracker gives no estimate. This does not confirm availability.

No transfer log has a transfer of any part of this IPv4 range.
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.
