No transfer record matches. ARIN's statistics show it available on 2026-07-15 and allocated (dated 2026-07-16) on 2026-07-17. The tracker saw this range released from hold on 2026-07-14 (2605:1C0::-2605:1C0:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF), so it appears to have been issued again from ARIN's pool.

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

ARIN's statistics show it reserved on 2026-07-13 and available on 2026-07-15. ARIN took it out of its reserved (held) records; its statistics now give it the status 'available'. That is ARIN's own label: whether and when it is reissued is not confirmed.

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.
