No transfer record matches. ARIN's statistics show it available on 2022-06-15 and assigned (dated 2022-06-16) on 2022-06-17. The tracker saw this range released from hold on 2022-06-13 (AS836), so it appears to have been issued again from ARIN's pool.

ARIN's statistics now list it as 'available'; reissue not confirmed

ARIN's statistics show it reserved on 2022-06-12 and available on 2022-06-14. ARIN took it out of its reserved (held) records; its statistics now give it the status 'available'. The tracker saw it removed from registration on 2021-02-22, 476 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2021-08-22. 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 0000-00-00) on 2021-02-21 and reserved on 2021-02-23. 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 2021-08-22. This does not confirm availability.
