Possible future reissue candidate after hold
Removed from active registration. The tracker found it by comparing RIPE NCC's daily statistics. RIPE NCC's statistics show it assigned (dated 2026-05-01) on 2026-06-04 and reserved on 2026-06-05. Public sources do not distinguish a voluntary return, revocation, or reclamation. RIPE NCC publishes no fixed period for which it holds returned IPv4 before reissuing them, so the tracker gives no estimate. This does not confirm availability.

Likely issued from RIPE NCC-controlled inventory
No transfer record matches. RIPE NCC's statistics show it reserved on 2026-04-30 and assigned (dated 2026-05-01) on 2026-05-01. It moved from RIPE NCC's unissued pool to an active registration dated around that day, so it appears to be newly issued by RIPE NCC.

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.
