No transfer record matches. ARIN's statistics show it available on 2024-01-04 and assigned (dated 2024-01-05) on 2024-01-06. The tracker saw this range released from hold on 2023-12-27 (AS19330), 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 2023-12-26 and available on 2023-12-28. 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 2018-10-09, 1905 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Hold estimate
Estimated hold end 2019-04-09. 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 2016-05-02) on 2018-10-08 and reserved on 2018-10-10. 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 2019-04-09. This does not confirm availability.

ARIN's statistics show it reserved on 2016-05-01 and assigned (dated 2016-05-02) on 2016-05-03. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS19330. The issuance is explained on that line.

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 2000-12-18) on 2016-03-15 and reserved on 2016-03-17. Public sources do not distinguish a voluntary return, revocation, or reclamation.

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.
