No transfer record matches. ARIN's statistics show it reserved on 2015-04-12 and allocated (dated 2015-04-13) on 2015-04-14. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

Part of the issuance reported the same day

ARIN's statistics show it reserved on 2015-04-12 and allocated (dated 2015-04-13) on 2015-04-14. ARIN removed its own pool record for this range as part of issuing it: the same report adds 158.222.16.0-158.222.31.255. The issuance is explained on that line.

ARIN's statistics now list it as 'available'; reissue not confirmed

ARIN's statistics show it reserved on 2014-07-27 and available on 2014-07-29. ARIN took it out of its reserved (held) records; its statistics now give it the status 'available'. That is ARIN's own label: whether and when it is reissued is not confirmed.

No effect on ARIN applicant inventory

ARIN-Issued lists it as "Remove", but ARIN's statistics show the same record before and after (reserved). Another change to this range was reported the day before or after (2014-07-23: Remove 158.222.16.0-158.222.31.255), so the before-and-after statistics may include it.

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.
