Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it reserved on 2024-11-18 and assigned (dated 2024-11-19) on 2024-11-20. The tracker saw this range released from hold on 2024-11-18 (AS20118), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2024-11-18: Remove AS20118), so the before-and-after statistics may include it.

ARIN's statistics show it reserved on 2024-11-17 and assigned (dated 2024-11-19) on 2024-11-19. ARIN removed its own pool record for this range and the range is now registered, but the same report doesn't list it as added. Another change to this range was reported the day before or after (2024-11-19: Add AS20118), so the before-and-after statistics may include it.

Hold estimate
Estimated hold end 2021-02-10. 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 2014-03-10) on 2020-08-09 and reserved on 2020-08-11. 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 2021-02-10. This does not confirm availability.

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.
