Hold estimate
Estimated hold end 2023-07-07. 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 2000-12-12) on 2023-05-07 and reserved on 2023-05-09. 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 2023-07-07. This does not confirm availability.

No transfer record matches. ARIN's statistics show it allocated (dated 2000-12-12) on 2018-11-19 and assigned (dated 2018-11-20) on 2018-11-21. The registration was replaced with one for a different holder record, and public sources don't say why (a transfer not yet logged, a return and reissue, or an organization record change).

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.
