No transfer record matches. The RIPE NCC's statistics show it available on 2022-07-21 and allocated (dated 2022-07-22) on 2022-07-22. The tracker saw this range released from hold on 2022-07-21 (AS203888), 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 (2022-07-21: Released AS203888), so the before-and-after statistics may include it.

The RIPE NCC's statistics show it reserved on 2022-07-20 and available on 2022-07-21. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2022-07-22: Added AS203888), so the before-and-after statistics may include it.

The RIPE NCC's statistics show it reserved on 2019-12-02 and available on 2019-12-03. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2019-06-06, 180 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2019-12-03. 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 2015-10-12) on 2019-06-05 and reserved on 2019-06-06. 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 2019-12-03. This does not confirm availability.

No transfer record matches. The RIPE NCC's statistics show it available on 2015-10-11 and allocated (dated 2015-10-12) on 2015-10-12. 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.
