ARIN's statistics show it reserved on 2025-11-19 and allocated (dated 2025-11-20) on 2025-11-21. ARIN removed its own pool record for this range as part of issuing it: the same report adds 142.249.104.0-142.249.107.255. The issuance is explained on that line.

Hold estimate
Estimated hold end 2026-05-20. Possible reissue candidate after this date; not confirmed available.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it assigned (dated 2024-01-18) on 2025-11-19 and reserved on 2025-11-21. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed ASNs for 6 calendar months before reissuing them, so the estimated hold end is 2026-05-20. This does not confirm availability. Since mid-2024, ARIN has released many ASNs within two months, before the 6 calendar months were up, so the release can come sooner.
