Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it available on 2025-10-22 and assigned (dated 2025-10-23) on 2025-10-24. The tracker saw this range released from hold on 2025-10-14 (AS17294), 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 2025-10-13 and available on 2025-10-15. ARIN took it out of its reserved (held) records; its statistics now give it the status 'available'. The tracker saw it removed from registration on 2025-08-19, 56 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2026-02-19. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it assigned (dated 2000-08-16) on 2025-08-18 and reserved on 2025-08-20. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed ASNs for 6 calendar months before reissuing them, so the estimated hold end is 2026-02-19. This does not confirm availability. Since mid-2024, ARIN has released many ASNs within two months, before the 6 calendar months were up, so the release can come sooner.

ARIN's transfer log records a merger, acquisition or reorganization from Colorado Alliance of Research Libraries (ARIN) to CARL Corporation (ARIN) on 2019-04-18 15:08 UTC. The registration changed hands; it is not a new allocation from ARIN. ARIN-Issued and ARIN's statistics don't show this change; only the transfer log records 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.
