No transfer record matches. ARIN's statistics show it reserved on 2023-05-02 and assigned (dated 2023-05-03) on 2023-05-04. The tracker saw this range removed from registration on 2020-11-09 (AS579), so it appears to have been issued again from ARIN's pool.

Part of the issuance reported the same day

ARIN's statistics show it reserved on 2023-05-02 and assigned (dated 2023-05-03) on 2023-05-04. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS579. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2021-05-09. 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 2009-07-21) on 2020-11-08 and reserved on 2020-11-10. 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 2021-05-09. This does not confirm availability.
