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

RIPE NCC's statistics show it reserved on 2026-05-04 and available on 2026-05-05. RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. That is 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 (2026-05-06: Added 164.40.232.0/24), so the before-and-after statistics may include it.

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.
