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 2022-04-25) on 2026-11-08 and reserved on 2026-11-09. 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 2027-05-08. This does not confirm availability.

The RIPE NCC's statistics show it reserved on 2022-04-22 and available on 2022-04-23. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2021-10-25, 180 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed.

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 2011-11-08) on 2011-11-08 and reserved on 2011-11-09. 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. Another change to this range was reported the day before or after (2011-11-08: Added AS57481), so the before-and-after statistics may include it.
