Hold estimate
Estimated hold end 2025-11-07. 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 2021-04-21) on 2025-09-07 and reserved on 2025-09-09. 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 2025-11-07. This does not confirm availability.

Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it reserved on 2021-04-20 and allocated (dated 2021-04-21) on 2021-04-22. The tracker saw this range released from hold on 2012-09-19 (149.112.0.0-149.112.255.255), so it appears to have been issued again from ARIN's pool.

RDAP lookups
Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
