Hold estimate
Estimated hold end 2027-04-26. 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 2022-11-08) on 2026-10-27 and reserved on 2026-10-28. 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 2027-04-26. This does not confirm availability.

No transfer record matches. The RIPE NCC's statistics show it available on 2022-11-07 and allocated (dated 2022-11-08) on 2022-11-08. The tracker saw this range released from hold on 2020-05-10 (AS201507), 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 2020-05-09 and available on 2020-05-10. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2019-11-12, 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 2014-10-08) on 2019-11-11 and reserved on 2019-11-12. 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 2020-05-10. This does not confirm availability.

No transfer record matches. The RIPE NCC's statistics show it available on 2014-10-07 and allocated (dated 2014-10-08) on 2014-10-08. It moved from the RIPE NCC's unissued pool to an active registration dated around that day, so it appears to be newly issued by the RIPE NCC.
