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.

2025-12-09 ARIN + Add Apparent reissuance of previously removed resource Strong inference

ARIN-Issued: Add AS394721
Inventory: Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it reserved on 2025-12-08 and assigned (dated 2025-12-09) on 2025-12-10. The tracker saw this range removed from registration on 2017-11-07 (AS394721), so it appears to have been issued again from ARIN's pool.

2025-12-09 ARIN − Remove Change to ARIN's own pool record Strong inference

ARIN-Issued: Remove AS394721
Inventory: Part of the issuance reported the same day

ARIN's statistics show it reserved on 2025-12-08 and assigned (dated 2025-12-09) on 2025-12-10. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS394721. The issuance is explained on that line.

Inventory: Possible future reissue candidate after hold
Hold estimate: Estimated hold end 2018-05-07. 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 2016-06-06) on 2017-11-06 and reserved on 2017-11-08. 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 2018-05-07. This does not confirm availability.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics.

2015-12-03 ARIN + Add Apparent new issuance Strong inference

ARIN-Issued: Add AS394721
Inventory: Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it available on 2015-12-02 and assigned (dated 2015-12-03) on 2015-12-04. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

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.
