Hold estimate
Estimated hold end 2027-04-12. 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 2025-10-03) on 2026-10-13 and reserved on 2026-10-14. 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 2027-04-12. This does not confirm availability.

No transfer record matches. The RIPE NCC's statistics show it available on 2025-10-02 and allocated (dated 2025-10-03) on 2025-10-03. The tracker saw this range released from hold on 2025-09-14 (AS204992), so it appears to have been issued again from the RIPE NCC's pool.

The RIPE NCC's statistics now list it as 'available'; reissue not confirmed

The RIPE NCC's statistics show it reserved on 2025-09-13 and available on 2025-09-14. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2025-03-18, 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 2022-06-28) on 2025-03-17 and reserved on 2025-03-18. 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 2025-09-14. This does not confirm availability.

No transfer record matches. The RIPE NCC's statistics show it available on 2022-06-27 and allocated (dated 2022-06-28) on 2022-06-28. The tracker saw this range released from hold on 2022-06-27 (AS204992), 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 (2022-06-27: Released AS204992), so the before-and-after statistics may include it.

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 2017-11-23) on 2021-12-28 and reserved on 2021-12-29. 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 2022-06-27. This does not confirm availability.
