Gigabyte — ~25 prefixes (MA-L) across name variants; OUI = brand (motherboard-NIC caveat)
Summary
- // what this is
- Giga-Byte Technology is registered to MAC prefix
18:C0:4Dand 24 more in the IEEE OUI database. When a device's MAC address begins with18:C0:4D, that block was registered by Giga-Byte Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A Gigabyte OUI maps to Gigabyte-branded hardware; on custom builds it identifies the Gigabyte motherboard's onboard NIC, not the system brand.
About this vendor.
Gigabyte's MAC footprint spans IEEE registrant variants that should be normalized to one canonical vendor: "Giga-Byte Technology Co., Ltd." (~24 blocks), "GIGA-BYTE TECHNOLOGY CO.,LTD.", and "Giga-Byte" (~1). A verified sample is 18:C0:4D, registered in Pin-Jen City, Taoyuan, Taiwan. These OUIs appear on motherboards, graphics cards, laptops (the Aorus and Aero lines), desktops, mini-PCs (Brix), and monitors. Like MSI, a Gigabyte OUI generally maps to the Gigabyte brand, but the network interface is often on a Gigabyte motherboard, so on a custom-built PC the OUI may identify the board maker rather than the whole-system brand. Gigabyte's Aorus sub-brand covers much of its gaming hardware. For triage, a Gigabyte OUI maps to Gigabyte-branded hardware, but on custom builds it identifies the Gigabyte motherboard's onboard NIC rather than the system brand.

- Special note
- OUI generally maps to the Gigabyte brand, but the NIC is often on a Gigabyte motherboard — on a custom-built PC the OUI may identify the board maker rather than the whole-system brand. Normalize the registrant variants to one canonical vendor. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
