ARIN's statistics show it reserved on 2025-10-05 and allocated (dated 2025-10-06), reserved on 2025-10-07. ARIN removed its own pool record for this range as part of issuing it: the same report adds 67.210.0.0-67.210.3.255, 67.210.4.0-67.210.7.255, 67.210.12.0-67.210.15.255. The issuance is explained on those lines.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2015-01-03. 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 2013-06-17) on 2014-11-03 and reserved on 2014-11-05. 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 2015-01-03. This does not confirm availability.

No transfer record matches. ARIN's statistics show it not listed on 2013-06-16 and allocated (dated 2013-06-17) on 2013-06-18. It wasn't in ARIN's statistics before, so it wasn't ARIN's unissued inventory; it may have come from another registry in a transfer not yet in the log.

ARIN's statistics now list it as 'available'; reissue not confirmed
ARIN's statistics show it reserved on 2013-06-10 and available on 2013-06-12. ARIN took it out of its reserved (held) records; its statistics now give it the status 'available'. The tracker saw it removed from registration on 2013-03-12, 91 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

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.
