Hold estimate
Estimated hold end 2027-05-09. 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 2015-06-26) on 2026-11-08 and reserved on 2026-11-10. 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 2027-05-09. 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.

No transfer record matches. ARIN's statistics show it reserved on 2015-06-25 and assigned (dated 2015-06-26) on 2015-06-27. The tracker saw this range removed from registration on 2015-02-10 (AS40228), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2015-06-25 and assigned (dated 2015-06-26) on 2015-06-27. ARIN removed its own pool record for this range as part of issuing it: the same report adds AS40228. The issuance is explained on that line.
