ARIN's statistics show it reserved on 2018-03-28 and allocated (dated 2018-03-29), reserved on 2018-03-30. ARIN removed its own pool record for this range as part of issuing it: the same report adds 161.129.30.0-161.129.30.255, 161.129.48.0-161.129.55.255, 161.129.60.0-161.129.60.255, 161.129.61.0-161.129.61.255 and 14 more. The issuance is explained on those lines. Another change to this range was reported the day before or after (2018-03-30: Remove 161.129.29.0-161.129.29.255; 2018-03-30: Remove 161.129.32.0-161.129.47.255; 2018-03-30: Remove 161.129.62.0-161.129.62.255), 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.
