A4:D9:C6 identifies an assignment to Airpro Technology Ltd
Summary
- // what this is
- Airpro Technology is registered to MAC prefix
A4:D9:C6in the IEEE OUI database. When a device's MAC address begins withA4:D9:C6, that block was registered by Airpro Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A literal match to A4:D9:C6 fixes the first-byte Group and Local bits at zero. The 24-bit suffix space contains 16,777,216 possible values; this is not a device or shipment count. RFC 7042 describes MAC address and prefix interpretation.
About this vendor.
A MAC address beginning A4:D9:C6 matches the IEEE MA-L assignment recorded to Airpro Technology Ltd. This identifies the registry assignment associated with the prefix; it does not establish the device type, product, current vendor identity, or safety of a device using a matching address.
The prefix is 24 bits long, leaving 24 bits, or 16,777,216 possible suffix values. That is a mathematical address-space count, not a count of devices or shipments. The IEEE record provides no assignment date.
Under RFC 7042’s interpretation, the first-byte Group bit and Local bit for this exact prefix are both zero. Those bits are fixed for a literal A4:D9:C6 prefix match; changing either bit produces a different prefix. A captured matching MAC can support identification of this assignment, but not the identity or characteristics of a particular device.
