No transfer record matches. The RIPE NCC's statistics show it available on 2023-02-28 and allocated (dated 2023-03-01) on 2023-03-01. The tracker saw this range released from hold on 2023-02-28 (AS57974), so it appears to have been issued again from the RIPE NCC's pool. Another change to this range was reported the day before or after (2023-02-28: Released AS57974), so the before-and-after statistics may include it.

The RIPE NCC's statistics show it reserved on 2023-02-27 and available on 2023-02-28. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2022-09-01, 180 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2023-03-01: Added AS57974), so the before-and-after statistics may include it.

Hold estimate

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 2021-05-06) on 2022-08-31 and reserved on 2022-09-01. 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 2023-02-28. This does not confirm availability.

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.
