- Hold estimate
- Earliest estimated hold expiration 2026-05-29. 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 allocated (dated 1991-09-17) on 2026-03-29 and not listed on 2026-03-31. Being gone from ARIN's statistics entirely can also mean it moved to another registry. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 for 60 days before reissuing them, so the earliest estimated hold expiration is 2026-05-29. This does not confirm availability.
