No transfer record matches. ARIN's statistics show it reserved on 2025-10-07 and assigned (dated 2025-10-08) on 2025-10-09. The tracker saw this range removed from registration on 2024-11-11 (AS2730), so it appears to have been issued again from ARIN's pool.

Part of the issuance reported the same day
ARIN's statistics show it reserved on 2025-10-07 and assigned (dated 2025-10-08) on 2025-10-09. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS2730. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2025-05-11. 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 2009-08-31) on 2024-11-10 and reserved on 2024-11-12. 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 2025-05-11. 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.

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.
