ASRock — 7 prefixes (MA-L); motherboard/mini-PC maker, OUI = brand (motherboard-NIC caveat)
Summary
- // what this is
- ASRock Incorporation is registered to MAC prefix
70:85:C2and 6 more in the IEEE OUI database. When a device's MAC address begins with70:85:C2, that block was registered by ASRock Incorporation — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- On a custom-built PC an ASRock OUI identifies the motherboard's onboard NIC, not a whole-system brand — infer an ASRock board (a discrete add-in NIC or USB adapter would carry a different OUI).
About this vendor.
ASRock holds about 7 MA-L blocks registered as "ASRock Incorporation" at 2F., No.37, Sec.2, Jhongyang S. Rd., Beitou District, Taipei, Taiwan, covering roughly 117.4 million addresses. Verified samples include 70:85:C2, A8:A1:59, 9C:6B:00, BC:5F:F4, and D0:50:99. These OUIs appear on motherboards, mini-PCs (the DeskMini and DeskMeet lines), graphics cards, and industrial PCs. ASRock was spun off from ASUS in 2002 and is associated with the Pegatron group. Like MSI and Gigabyte, an ASRock OUI generally maps to the ASRock brand, but the network interface is often on an ASRock motherboard, so on a custom-built PC the OUI identifies the board's onboard NIC rather than a whole-system brand. For triage, on a custom-built PC an ASRock OUI identifies the motherboard's onboard NIC, not a whole-system brand — so infer an ASRock board rather than a brand-name PC (a discrete add-in NIC or USB adapter would carry a different OUI).

- OUI generally maps to the ASRock brand, but the NIC is often on an ASRock motherboard — on a custom-built PC the OUI identifies the board's onboard NIC, not a whole-system brand. Spun off from ASUS (2002); associated with Pegatron. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
