Marvell's MAC footprint surfaces under two literal registrant strings: "MARVELL SEMICONDUCTOR, INC." (comma, all-caps, registered at 645 Almanor Avenue, Sunnyvale, CA) and "Marvell Semiconductors" (no comma, registered at a former Aquantia site in Irvine, CA). Verified samples are 00:50:43 (MARVELL SEMICONDUCTOR, INC.) and F4:C7:AA (Marvell Semiconductors). These OUIs appear on Wi-Fi chipsets (game consoles, IoT, APs), Ethernet and switch silicon, storage controllers (SSD/HDD), and embedded processors. An important data-quality caveat for this entry: public lookup databases surface only about one block per literal "Marvell" string, which materially understates Marvell's true footprint, because most Marvell silicon ships under acquired-entity names (Cavium, Aquantia, Inphi, QLogic) and legacy strings that those databases don't aggregate — so the "~1 block" figure is a database-aggregation artifact, not a true total. The key analyst point is the chipset pattern: a Marvell OUI identifies a device built on Marvell silicon regardless of brand, and Marvell Wi-Fi historically appeared in game consoles and streaming devices. For triage, a Marvell OUI usually means the NIC, radio, or controller silicon is Marvell while the device brand is determined elsewhere.

- Special note
- A Marvell OUI is a chipset-OUI flag; Marvell Wi-Fi historically appeared in game consoles and streaming devices. IMPORTANT: the literal-string block count (~1 each) materially UNDERSTATES Marvell's real OUI holdings — most silicon ships under Cavium/Aquantia/Inphi/QLogic and legacy strings the databases don't aggregate. Do NOT publish "~1 block" as a true total; it is a DB-aggregation artifact. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
