No transfer record matches. ARIN's statistics show it reserved on 2026-10-25 and assigned (dated 2026-10-26) on 2026-10-27. The tracker saw it removed from registration on 2018-04-10 (3121 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.

Part of the issuance reported the same day

ARIN's statistics show it reserved on 2026-10-25 and assigned (dated 2026-10-26) on 2026-10-27. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS22538. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2018-10-10. 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 2009-11-06) on 2018-04-09 and reserved on 2018-04-11. 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 2018-10-10. This does not confirm availability.
