onsemi's MAC footprint spans IEEE registrants that should be aliased to one family: "ON Semiconductor" (~2 blocks) and "Quantenna Communcations, Inc." (1 block — note the IEEE record's misspelling "Communcations"). Verified onsemi samples include 60:C0:BF and F4:00:46; the Quantenna sample is 00:26:86 (registered at 3450 W. Warren Ave., Fremont, CA). onsemi's own address is in Phoenix/Scottsdale, AZ. These OUIs appear on power semiconductors, image sensors, Quantenna high-end Wi-Fi silicon (found in some routers and gateways), automotive, and industrial parts. The corporate history: onsemi was spun out of Motorola's Semiconductor Components Group (founded 1999, IPO 2000), acquired Fairchild Semiconductor (2016), and completed its Quantenna Communications acquisition on 2019-06-19 (~$1.07 billion equity value, $24.50/share all-cash); its board then approved exiting the legacy Quantenna Wi-Fi business on 2022-09-16 (a sub-sector that was under 3% of 2021 revenue). The legal trademark holder is "Semiconductor Components Industries, LLC (SCILLC)." The key analyst point is the chipset pattern: a Quantenna 00:26:86 OUI signals a high-end Wi-Fi radio (often the bridge interface) inside a router or gateway, while onsemi's own two blocks are rare and point to industrial/embedded silicon. For triage, treat a Quantenna OUI as a high-end Wi-Fi chipset signal inside a router/gateway, not a brand.

- Special note
- A Quantenna 00:26:86 OUI signals a high-end Wi-Fi radio (often the bridge br0 interface) inside a router/gateway — a chipset signal, not a brand. onsemi's own two blocks are rare (industrial/embedded). Legal trademark holder is "Semiconductor Components Industries, LLC (SCILLC)" — a distinct registrant record may exist. The IEEE registry publishes no assignment dates, so none is stated here.
