Removed from active registration. The tracker found it by comparing RIPE NCC's daily statistics. RIPE NCC's statistics show it allocated (dated 2014-04-30) on 2026-04-15 and reserved on 2026-04-16. Public sources do not distinguish a voluntary return, revocation, or reclamation. RIPE NCC publishes no fixed period for which it holds returned IPv6 before reissuing them, so the tracker gives no estimate. This does not confirm availability.

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.
