Aquantia Corporation — 2 prefixes (MA-L)

Aquantia Corporation holds two IEEE MA-L blocks — 00:17:B6 and 30:0E:E3 — both registered to "Aquantia Corporation" at 700 Tasman Drive, Milpitas, CA 95035, US. Aquantia was a Silicon Valley semiconductor company that designed Multi-Gigabit Ethernet PHY and controller silicon: the AQtion / AQC10x family (AQC107, AQC108) that powers 2.5G/5G/10GbE network cards, plus automotive Multi-Gig PHYs. Its own AQtion NICs (AQN-107, AQN-108) and third-party cards from Dell, AKiTiO and others are built on these controllers, and the Linux "atlantic" driver (originally in Aquantia's public GitHub) supports them. Aquantia went public on NASDAQ (ticker AQ) in November 2017 and was acquired by Marvell Technology in a deal that closed September 19, 2019 for roughly $452M cash. So an Aquantia OUI reliably points to a workstation/PC multi-gigabit NIC or an embedded Multi-Gig PHY — a real product footprint, not a bare shell registration. Note that a well-documented Linux kernel vulnerability, CVE-2021-43975, affects the atlantic driver used by these cards.

IEEE assignment

2 prefixes → Aquantia Corporation, registered Milpitas, CA, US [Confirmed] — IEEE MA-L (local cached the IEEE MA-L registry)

Registry / block size

MA-L (24-bit OUI); holds 2 IEEE prefixes (00:17:B6 and 30:0E:E3). No MA-M (the IEEE MA-M registry) or MA-S (the IEEE MA-S registry) blocks found. [Confirmed] — IEEE MA-L (the IEEE MA-M registry, the IEEE MA-S registry cross-checked). NOTE: IEEE's public OUI data publishes NO assignment/registration date; any "date registered" on third-party tools is a database artifact, not an IEEE fact.

Security note

CVE-2021-43975 — out-of-bounds write in hw_atl_utils_fw_rpc_wait() in the Linux "atlantic" driver for Aquantia AQtion cards (kernel through 5.15.2); local/attacker-controls-device class, patched upstream and by major distros. Related atlantic-driver CVEs: CVE-2021-4202, CVE-2021-4197.

Analyst note

An Aquantia OUI identifies a genuine multi-gigabit NIC or embedded PHY. Since the atlantic driver moved to Marvell maintenance post-2019, newer silicon may register under Marvell rather than Aquantia; both prefixes here remain Aquantia-registered in the IEEE data.
