2021-01-05 RIPE NCC Released Released from hold (the RIPE NCC lists it as 'available') Strong inference

Statistics: AS35517 reserved on 2021-01-04, available on 2021-01-05
Inventory: The RIPE NCC's statistics now list it as 'available'; reissue not confirmed

The RIPE NCC's statistics show it reserved on 2021-01-04 and available on 2021-01-05. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2020-07-09, 180 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed.

2020-07-09 RIPE NCC − Deregistered Removed (return, revocation or reclamation not publicly distinguishable) Strong inference

Statistics: AS35517 allocated on 2020-07-08, reserved on 2020-07-09
Inventory: Possible future reissue candidate after hold
Hold estimate: Estimated hold end 2021-01-05. 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 2019-02-12) on 2020-07-08 and reserved on 2020-07-09. 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 2021-01-05. This does not confirm availability.

Statistics: AS35517 available on 2019-02-11, allocated on 2019-02-12
Inventory: Likely issued from RIPE NCC-controlled inventory

No transfer record matches. The RIPE NCC's statistics show it available on 2019-02-11 and allocated (dated 2019-02-12) on 2019-02-12. The tracker saw this range released from hold on 2015-11-25 (AS35517), so it appears to have been issued again from the RIPE NCC's pool.

The RIPE NCC's statistics show it reserved on 2015-11-24 and available on 2015-11-25. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2014-02-26, 637 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed.

Statistics: AS35517 allocated on 2014-02-25, reserved on 2014-02-26
Inventory: Possible future reissue candidate after hold

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 2005-08-25) on 2014-02-25 and reserved on 2014-02-26. 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.

Transfer records

No transfer log has a transfer of any part of this ASN.

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.
