Timeline (4)

Every change the tracker has found, newest first. It covers ARIN from 2008-12-01, the RIPE NCC from 2010-04-23, APNIC from 2008-02-15, LACNIC from 2012-06-29 and AFRINIC from 2012-10-03.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2027-05-09. 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 2025-06-03) on 2026-11-08 and reserved on 2026-11-10. 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 2027-05-09. This does not confirm availability. Since mid-2024, ARIN has released many ASNs within two months, before the 6 calendar months were up, so the release can come sooner.

Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it available on 2025-06-02 and assigned (dated 2025-06-03) on 2025-06-04. The tracker saw this range released from hold on 2025-05-23 (AS393881), 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 2025-05-22 and available on 2025-05-24. 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 2024-09-09, 256 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.
