Murata holds about 76 IEEE blocks (MA-L and MA-S) registered as "Murata Manufacturing Co., Ltd." at Higashikotari, Nagaokakyo-shi, Kyoto, Japan. Verified samples include FC:84:A7, 44:A7:CF, D0:17:69, F0:27:65, and 60:F1:89. These OUIs appear on Wi-Fi/Bluetooth modules embedded in smartphones, IoT devices, smart-home gear, and wearables, as well as on capacitors and other passive components (Murata is a global components giant that built up its wireless-module business partly via acquisitions). Like AzureWave, a Murata OUI identifies a Murata wireless module regardless of the device brand — and Murata modules are extremely common across a huge range of devices. For triage, a Murata OUI means "a Murata Wi-Fi/BT module is inside," with the host being any brand of phone, wearable, or IoT device — a high-frequency module signal that is not a brand identifier and not inherently a rogue-device indicator.

- Special note
- Like AzureWave, a Murata OUI identifies a Murata wireless module REGARDLESS of device brand — extremely common across a huge range of devices. The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
- Related vendors
- none significant (module/component supplier to many brands)
- Analyst note
- A Murata OUI means "a Murata Wi-Fi/BT module is inside" — the host could be any brand of phone, wearable, or IoT device. High-frequency module signal; not a brand identifier and not inherently rogue.
