No transfer record matches. The RIPE NCC's statistics show it available on 2021-06-24 and allocated (dated 2021-06-25) on 2021-06-25. The tracker saw this range released from hold on 2021-06-22 (AS52112), 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 2021-06-21 and available on 2021-06-22. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2020-12-24, 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 2018-06-13) on 2020-12-23 and reserved on 2020-12-24. 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 2021-06-22. This does not confirm availability.

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 2010-12-29) on 2017-12-12 and reserved on 2017-12-13. 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 2018-06-11. This does not confirm availability.

No transfer record matches. The RIPE NCC's statistics show it available on 2010-12-29 and allocated (dated 2010-12-29) on 2010-12-30. 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.

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.
