Hold estimate
Estimated hold end 2021-12-07. 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 2012-11-07) on 2021-06-06 and reserved on 2021-06-07. 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 2021-12-07. This does not confirm availability.

No transfer record matches. LACNIC's statistics show it available on 2012-11-06 and allocated (dated 2012-11-07) on 2012-11-07. 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.
