Hold estimate
Estimated hold end 2027-05-03. 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 2019-03-29) on 2026-11-02 and reserved on 2026-11-04. 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 2027-05-03. 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 available on 2019-03-28 and assigned (dated 2019-03-29) on 2019-03-30. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.
