The RIPE NCC's statistics now list it as 'available'; reissue not confirmed
The RIPE NCC's statistics show it reserved on 2022-08-22 and available on 2022-08-23. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2022-02-24, 180 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed.

Hold estimate
Estimated hold end 2022-08-23. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. The tracker found it by comparing the RIPE NCC's daily statistics. The RIPE NCC's statistics show it allocated (dated 2017-09-15) on 2022-02-23 and reserved on 2022-02-24. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC holds returned, revoked and reclaimed ASNs for 180 days (six months), or longer while still routed, before reissuing them, so the estimated hold end is 2022-08-23. This does not confirm availability.

Likely issued from RIPE NCC-controlled inventory
No transfer record matches. The RIPE NCC's statistics show it available on 2017-09-14 and allocated (dated 2017-09-15) on 2017-09-15. The tracker saw this range released from hold on 2015-11-25 (AS41158), so it appears to have been issued again from the RIPE NCC's pool.

Possible future reissue candidate after hold
Removed from active registration. The tracker found it by comparing the RIPE NCC's daily statistics. The RIPE NCC's statistics show it allocated (dated 2006-06-22) on 2013-10-01 and reserved on 2013-10-02. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC's current hold for ASNs applies to removals from 2014-03-26 on, and this one came earlier, so the tracker gives no estimate. 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.
