Hold estimate
Estimated hold end 2027-04-16. 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 2001-02-09) on 2026-10-15 and reserved on 2026-10-17. 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 2027-04-16. 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.
