ABB Xiamen Low Voltage Equipment Co.,Ltd. MAC Prefix: Device Type Unknown
Summary
- // what this is
- ABB Xiamen Low Voltage Equipment is registered to MAC prefix
80:3B:2Ain the IEEE OUI database. When a device's MAC address begins with80:3B:2A, that block was registered by ABB Xiamen Low Voltage Equipment — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The 24-bit prefix leaves 24 suffix bits (16,777,216 possible values), which is not a device or shipment count. For the exact prefix, the first-byte Group and Local bits are both clear (0); changing either bit yields a different prefix. A matching address supports a registry-prefix match only, not a particular device, deployment, or safety state.
About this vendor.
A MAC address beginning 80:3B:2A is registered to ABB Xiamen Low Voltage Equipment Co.,Ltd.; the available evidence does not identify a device type. The IEEE MA-L record lists one assignment, 80:3B:2A, and indicates China. This identifies the registry entry associated with the prefix, not the current maker, model, deployment, or safety of a device.
The prefix is 24 bits long, leaving 24 bits, or 16,777,216 possible suffix values. That is a range of possible address values, not a count of devices or shipments. The first byte 80 has Group and Local bits both clear. Those bit values are fixed for an exact 80:3B:2A prefix match; changing either bit produces a different prefix. RFC 7042 explains the significance of these MAC address bits and prefix assignments.
A captured address that matches all three prefix bytes is consistent with this assignment. It cannot establish a particular device category or product. Assignment dates are unavailable in these IEEE CSV records.
