Hold estimate
Estimated hold end 2026-01-17. 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 2012-05-29) on 2025-07-20 and reserved on 2025-07-21. 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 2026-01-17. This does not confirm availability.

No transfer record matches. The RIPE NCC's statistics show it available on 2012-05-28 and allocated (dated 2012-05-29) on 2012-05-29. 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.
