The RIPE NCC's statistics now list it as 'available'; reissue not confirmed

The RIPE NCC's statistics show it reserved on 2026-10-19 and available on 2026-10-20. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2026-04-23, 180 days earlier. 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 (2026-10-21: Added 2001:67c:5c4::/48), so the before-and-after statistics may include it.
