Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it reserved on 2022-12-14 and assigned (dated 2022-12-15) on 2022-12-16. The tracker saw this range removed from registration on 2018-12-11 (AS22963), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2022-12-14 and assigned (dated 2022-12-15) on 2022-12-16. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS22963. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2019-06-11. 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 2012-07-19) on 2018-12-10 and reserved on 2018-12-12. 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 2019-06-11. 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. ARIN's statistics show it allocated (dated 2001-12-21) on 2011-12-12 and not issued on 2011-12-14. (Until 2013-03-05, ARIN's statistics list only what's issued.) 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 2012-06-13. This does not confirm availability.

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.
