Timeline (7)

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.

Inventory
Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2026-03-08. 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 2022-04-07) on 2025-09-07 and reserved on 2025-09-09. 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 2026-03-08. 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 reserved on 2022-04-06 and assigned (dated 2022-04-07) on 2022-04-08. The tracker saw this range removed from registration on 2020-12-07 (AS13387), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2022-04-06 and assigned (dated 2022-04-07) on 2022-04-08. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS13387. The issuance is explained on that line.

Hold estimate
Estimated hold end 2021-06-07. 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 2016-07-01) on 2020-12-06 and reserved on 2020-12-08. 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 2021-06-07. This does not confirm availability.

Inventory
No effect on ARIN applicant inventory

No transfer record matches. ARIN's statistics show it reserved on 2016-06-30 and assigned (dated 2016-07-01) on 2016-07-02. The tracker saw it removed from registration on 2015-10-13 (262 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.

Transfer records

No transfer log has a transfer of any part of this ASN.

RDAP lookups

Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
