Hold estimate

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 allocated (dated 2025-07-10) on 2026-10-22 and reserved on 2026-10-24. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2026-12-22. This does not confirm availability.

No transfer record matches. ARIN's statistics show it reserved on 2025-07-09 and allocated (dated 2025-07-10) on 2025-07-11. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.
