No transfer record matches. ARIN's statistics show it reserved on 2026-10-13 and assigned (dated 2026-10-14) on 2026-10-15. The tracker saw this range removed from registration on 2025-11-17 (AS55072), 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 2026-10-13 and assigned (dated 2026-10-14) on 2026-10-15. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS55072. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2026-05-17. 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 2013-06-04) on 2025-11-16 and reserved on 2025-11-18. 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 2026-05-17. 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.
