No transfer record matches. ARIN's statistics show it reserved on 2026-11-09 and assigned (dated 2026-11-10) on 2026-11-11. The tracker saw it removed from registration on 2021-11-08 (1828 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.

ARIN's statistics show it reserved on 2026-11-09 and assigned (dated 2026-11-10) on 2026-11-11. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS395270. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2022-05-08. 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 2016-06-13) on 2021-11-07 and reserved on 2021-11-09. 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 2022-05-08. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2016-06-12 and assigned (dated 2016-06-13) on 2016-06-14. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.
