Hold estimate

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 allocated (dated 2019-10-17) 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 IPv4 space for 60 days before reissuing it, so the estimated hold end is 2027-01-08. This does not confirm availability.

ARIN's transfer log records a transfer from Versaweb, LLC (ARIN) to Northern Safety Co., Inc. (ARIN) on 2019-10-17 14:31 UTC. ARIN-Issued lists it as "Add" because the registration changed hands; it is not a new allocation from ARIN.
