Lenovo's MAC footprint is fragmented across three lineages, which matters for normalization. The "Lenovo" registrant itself is small (about 4 blocks, Morrisville NC), while the much larger "Motorola Mobility LLC, a Lenovo Company" registrant holds about 122 blocks (Chicago, IL) — the explicit "a Lenovo Company" suffix in IEEE data reflects Lenovo's 2014 acquisition of Motorola Mobility from Google. Older ThinkPad-lineage blocks may still be IBM-registered from Lenovo's 2005 acquisition of IBM's PC division. These OUIs span ThinkPad/IdeaPad/Yoga/Legion laptops, desktops, Motorola moto/edge/razr smartphones, and ThinkSystem servers. Motorola Android phones support MAC randomization. The Motorola Mobility acquisition was announced 29 January 2014 and completed 30 October 2014 for a total purchase price at close of approximately US$2.91 billion. For triage, a "Motorola Mobility…a Lenovo Company" OUI is almost always a personal Android phone (BYOD/shadow-IT), while plain "Lenovo"/IBM-lineage OUIs indicate managed laptops or servers — a useful split for separating corporate endpoints from personal devices in DHCP logs.
- IEEE assignment
- ~4 prefixes → Lenovo (Morrisville, NC); ~122 → Motorola Mobility LLC, a Lenovo Company (Chicago, IL); some legacy IBM blocks [Confirmed] — IEEE MA-L
- Registry / block size

NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" from third-party tools is a database artifact, not an IEEE fact.
