Hold estimate
Estimated hold end 2027-04-20. 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 2015-10-27) on 2026-10-21 and reserved on 2026-10-22. 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 2027-04-20. This does not confirm availability.

No transfer record matches. The RIPE NCC's statistics show it available on 2015-10-26 and allocated (dated 2015-10-27) on 2015-10-27. 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.
