Removed from active registration. The tracker found it by comparing LACNIC's daily statistics. LACNIC's statistics show it assigned (dated 1993-11-24) on 2013-03-24 and available on 2013-03-25. 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.

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.
