No transfer record matches. ARIN's statistics show it reserved on 2014-07-08 and assigned (dated 2014-07-09) on 2014-07-10. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

ARIN's statistics show it reserved on 2014-07-08 and assigned (dated 2014-07-09) on 2014-07-10. ARIN removed its own pool record for this range as part of issuing it: the same report adds 208.88.236.0-208.88.239.255. 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 2013-11-17 and available on 2013-11-19. 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.

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.
