Airware — MAC prefix identifies an IEEE registry assignment
Summary
- // what this is
- Airware is registered to MAC prefix
E4:C6:2Bin the IEEE OUI database. When a device's MAC address begins withE4:C6:2B, that block was registered by Airware — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact prefix match identifies the MA-L registry assignment only; it does not establish a specific device, product, current vendor, deployment, or security state. The first octet E4 has Group bit 0 and Local bit 0. The 24-bit prefix leaves 24 suffix bits, or 16,777,216 possible values, which is not an observed device or shipment count.
About this vendor.
A MAC address beginning E4:C6:2B matches an IEEE MA-L assignment to Airware; the supplied evidence does not identify a device category or a product using it. A matching prefix establishes the registry assignment only, not the device’s current vendor, deployment, or security status.
The assignment is 24 bits long, leaving 24 bits for suffix values. The projection calculates 16,777,216 possible suffix values; this is an address-space count, not a count of devices, shipments, or observed traffic. The exact prefix match requires the first three octets E4:C6:2B.
For this prefix, the first octet E4 has Group bit 0 and Local bit 0. RFC 7042 describes those bits as distinguishing group and local address semantics; changing either bit changes the prefix and is not a variation within this fixed assignment. IEEE CSV records supplied here do not include assignment dates.
