Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it available on 2025-04-01 and assigned (dated 2025-04-02) on 2025-04-03. The tracker saw this range released from hold on 2025-03-18 (AS395712), 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 2025-03-17 and available on 2025-03-19. 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 2024-07-08, 253 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2025-01-08. 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 2022-02-08) on 2024-07-07 and reserved on 2024-07-09. 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 2025-01-08. 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.

No effect on ARIN applicant inventory
No transfer record matches. ARIN's statistics show it reserved on 2022-02-07 and assigned (dated 2022-02-08) on 2022-02-09. The tracker saw it removed from registration on 2021-04-05 (309 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.

ARIN's statistics show it reserved on 2022-02-07 and assigned (dated 2022-02-08) on 2022-02-09. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS395712. 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 2016-11-18) on 2021-04-04 and reserved on 2021-04-06. 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 2021-10-05. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2016-11-17 and assigned (dated 2016-11-18) on 2016-11-19. 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.
