Hold estimate
Estimated hold end 2027-05-02. 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 allocated (dated 2025-12-24) on 2026-11-01 and reserved on 2026-11-03. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv6 space for 6 calendar months before reissuing it, so the estimated hold end is 2027-05-02. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2025-12-23 and allocated (dated 2025-12-24) on 2025-12-25. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.
