Every change the tracker has found, newest first. It covers ARIN from 2008-12-01, the RIPE NCC from 2010-04-23, APNIC from 2008-02-15, LACNIC from 2012-06-29 and AFRINIC from 2012-10-03.
The RIPE NCC's transfer log records a transfer from CASTO GARCIA MANZANO, S.L.U. (RIPE NCC) to CAST-TELECOM SL (RIPE NCC) on 2021-02-25 19:00 UTC. The registration changed hands; it is not a new allocation from the RIPE NCC.

No transfer record matches. The RIPE NCC's statistics show it available on 2020-07-09 and allocated (dated 2020-07-10) on 2020-07-10. The tracker saw this range removed from registration on 2019-11-04 (2a0c:b580::/29), so it appears to have been issued again from the RIPE NCC's pool.

Hold estimate
Estimated hold end 2020-05-02. 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 2018-01-17) on 2019-11-03 and reserved on 2019-11-04. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC holds returned, revoked and reclaimed IPv6 space for 180 days (six months), or longer while still routed, before reissuing it, so the estimated hold end is 2020-05-02. This does not confirm availability.

No transfer record matches. The RIPE NCC's statistics show it available on 2018-01-16 and allocated (dated 2018-01-17) on 2018-01-17. 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.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv6 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.
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.
