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]

- 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.
