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 assigned (dated 2016-11-01) on 2016-11-05 and available, reserved on 2016-11-06. 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.

Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it available, reserved on 2016-10-31 and assigned (dated 2016-11-01) on 2016-11-01. 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.
