Likely issued from LACNIC-controlled inventory
No transfer record matches. LACNIC's statistics show it available on 2014-07-16 and assigned (dated 2014-07-17) on 2014-07-17. It moved from LACNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by LACNIC. Another change to this range was reported the day before or after (2014-07-16: Released 200.33.4.0/24), 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.
