Edgecore / Accton — ~17 prefixes (MA-L); white-box / open-networking ODM
Summary
- // what this is
- Edgecore Networks is registered to MAC prefix
CC:37:ABand 16 more in the IEEE OUI database. When a device's MAC address begins withCC:37:AB, that block was registered by Edgecore Networks — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An Edgecore/Accton OUI = a data-center / white-box switch (likely running an open NOS) or ODM-built networking hardware; the OUI may not match the apparent brand — treat as an open-networking / data-center infrastructure signal.
About this vendor.
Edgecore holds about 17 MA-L blocks registered as "Edgecore Networks Corporation" at 1 Creation Road 3, Hsinchu, Taiwan, alongside the parent "Accton Technology Corporation." Verified samples include CC:37:AB, E0:01:A6, 1C:EA:0B, 90:3C:B3, B8:6A:97, and A8:2B:B5. These OUIs appear on white-box / open-networking / bare-metal data-center switches (running SONiC, Cumulus, or other network operating systems), open-networking hardware, and Wi-Fi. The important structural point: Edgecore is Accton Technology's open-networking brand, and Accton is a major ODM/contract manufacturer, so an Accton/Edgecore OUI may appear on white-labeled gear sold under other brand names — a chipset/ODM-like distinction directly analogous to Tuya in the IoT space. For triage, an Edgecore/Accton OUI is a data-center / white-box switch (likely running an open NOS) or ODM-built networking hardware; the OUI may not match the apparent brand, so treat it as an open-networking / data-center infrastructure signal.

- Special note
- ODM signal — Edgecore is Accton's open-networking brand, and Accton is a major ODM/contract manufacturer, so an Accton/Edgecore OUI may appear on white-labeled gear sold under other brand names (analogous to Tuya in IoT). The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
