ARIN's statistics now list it as 'available'; reissue not confirmed
ARIN's statistics show it reserved on 2015-03-31 and available on 2015-04-02. 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 2015-01-06, 85 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2015-04-02: Add 64.137.0.0-64.137.127.255), so the before-and-after statistics may include it.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2015-03-07. 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 assigned (dated 2000-08-01) on 2015-01-05 and reserved on 2015-01-07. 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 2015-03-07. This does not confirm availability.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.
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.
