Part of the issuance reported the same day
ARIN's statistics show it reserved on 2024-12-22 and allocated (dated 2024-12-23) on 2024-12-24. ARIN removed its own pool record for this range as part of issuing it: the same report adds 216.234.130.0-216.234.131.255, 216.234.132.0-216.234.132.255. The issuance is explained on those lines.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2012-11-16. 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 2012-05-01) on 2012-09-16 and not issued on 2012-09-18. (Until 2013-03-05, ARIN's statistics list only what's issued.) 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 2012-11-16. This does not confirm availability.

No transfer record matches. ARIN's statistics show it allocated (dated 1999-08-27) on 2012-04-30 and allocated (dated 2012-05-01) on 2012-05-02. (Until 2013-03-05, ARIN's statistics list only what's issued.) 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).

No transfer log has a transfer of any part of this IPv4 range.
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.
