LACNIC's statistics now list it as 'available'; reissue not confirmed
LACNIC's statistics show it reserved on 2020-11-30 and available on 2020-12-01. LACNIC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2020-06-10, 174 days earlier. 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 (2020-12-02: Added 177.53.212.0/22), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2020-12-10. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. The tracker found it by comparing LACNIC's daily statistics. LACNIC's statistics show it allocated (dated 2011-05-27) on 2020-06-09 and reserved on 2020-06-10. Public sources do not distinguish a voluntary return, revocation, or reclamation. LACNIC holds returned, revoked and reclaimed IPv4 space for 6 calendar months before reissuing it, so the estimated hold end is 2020-12-10. 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.
