No effect on LACNIC applicant inventory
No transfer record matches. LACNIC's statistics show it reserved on 2024-06-02 and allocated (dated 2015-05-11) on 2024-06-03. The tracker saw it removed from registration on 2024-05-13 (21 days earlier), and it is back with the same holder record it had before, so it went back to its previous holder rather than to a new one: most likely a suspension lifted, a reinstatement or a correction.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2024-11-13. 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 2015-05-11) on 2024-05-12 and reserved on 2024-05-13. 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 2024-11-13. This does not confirm availability.

Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it available on 2015-05-10 and allocated (dated 2015-05-11) on 2015-05-11. It moved from LACNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by LACNIC. Another change to this range was reported the day before or after (2015-05-10: Released 138.99.188.0/22), so the before-and-after statistics may include it.

LACNIC's statistics now list it as 'available'; reissue not confirmed
LACNIC's statistics show it reserved on 2015-05-09 and available on 2015-05-10. 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. Another change to this range was reported the day before or after (2015-05-11: Added 138.99.188.0/22), so the before-and-after statistics may include it.

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.
