74:A3:4Aand 1 more in the IEEE OUI database. When a device's MAC address begins with74:A3:4A, that block was registered by ZIMI — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Both prefixes are 24 bits, with 24 suffix bits (16,777,216 possible values) each. Their first-octet Group and Local bits are fixed at zero; changing either bit yields a different prefix. Possible suffix values are not a device or shipment count. A match identifies a registry assignment, not a specific device, deployment, prevalence, or security state.
About this vendor.
A MAC address beginning with 74:A3:4A or 6C:D3:EE identifies an IEEE MA-L assignment to ZIMI CORPORATION; the supplied evidence does not identify a device category or a specific product using either prefix.
ZIMI’s company page describes a business founded in 2012, renamed ZMI in October 2013, and active in phone accessories, Bluetooth earphones, and smart hardware. Its listed catalog includes power banks, chargers, wireless chargers, USB cables, household appliances, and batteries. Xiaomi is described as acquiring a 49.91% stock right in ZMI in May 2020; this does not establish a product-to-prefix connection.
Both assignments are 24-bit prefixes, leaving 24 suffix bits, or 16,777,216 possible suffix values per prefix. In each literal prefix, the first-octet Group and Local bits are zero. Changing either bit produces a different prefix; these fixed bits do not describe variation within the assigned prefix. Possible suffix values are not a count of devices or shipments. A match supports the registry assignment only, not a particular device, deployment, traffic prevalence, or security state.
