ARIN's transfer log records a merger, acquisition or reorganization from Dynamic Signal, Inc. (ARIN) to Firstup, Inc. (ARIN) on 2024-03-21 20:10 UTC. The registration changed hands; it is not a new allocation from ARIN. ARIN-Issued and ARIN's statistics don't show this change; only the transfer log records it.

Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it reserved on 2018-06-11 and assigned (dated 2018-06-12) on 2018-06-13. The tracker saw this range released from hold on 2018-06-11 (161.129.72.0-161.129.72.255), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2018-06-11: Remove 161.129.72.0-161.129.72.255), so the before-and-after statistics may include it.

ARIN's statistics show it reserved on 2018-06-11 and assigned (dated 2018-06-12) on 2018-06-13. ARIN removed its own pool record for this range as part of issuing it: the same report adds 161.129.72.0-161.129.72.255. The issuance is explained on that line. Another change to this range was reported the day before or after (2018-06-11: Remove 161.129.72.0-161.129.72.255), so the before-and-after statistics may include it.

ARIN-Issued lists it as "Remove", but ARIN's statistics show the same record before and after (reserved). Another change to this range was reported the day before or after (2018-06-12: Remove 161.129.72.0-161.129.72.255; 2018-06-12: Add 161.129.72.0-161.129.72.255), so the before-and-after statistics may include it.

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.
