ARIN's transfer log records a merger, acquisition or reorganization from Rockwell Collins, Inc. (ARIN) to RTX Corporation (ARIN) on 2026-09-01 15:37 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.

No transfer record matches. ARIN's statistics show it assigned (dated 1999-12-03) on 2011-03-20 and assigned (dated 2011-03-21) on 2011-03-22. (Until 2013-03-05, ARIN's statistics list only what's issued.) The registration was replaced with one for a different holder record, and public sources don't say why (a transfer not yet logged, a return and reissue, or an organization record change).

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.
