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

LACNIC's statistics show it reserved on 2017-03-08 and available on 2017-03-09. LACNIC moved it from its reserved (held) records to the status it calls 'available'. That is LACNIC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2017-03-10: Added 45.4.172.0/22), 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.
