Advanced Automotive Antennas — MAC prefix identifies registry assignment
Summary
- // what this is
- Advanced Automotive Antennas is registered to MAC prefix
E8:48:1Fin the IEEE OUI database. When a device's MAC address begins withE8:48:1F, that block was registered by Advanced Automotive Antennas — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A captured MAC address matching E8:48:1F supports attribution to the IEEE MA-L registry assignment only. This is a 24-bit prefix with 24 suffix bits and 16,777,216 possible suffix values; that value is not a device or shipment count. The prefix has Group bit 0 and Local bit 0 in its first octet E8. A different value for either bit is a different prefix.
About this vendor.
A MAC address beginning E8:48:1F matches the IEEE MA-L assignment to Advanced Automotive Antennas. This identifies the registered assignment only; the supplied evidence does not establish a device category or show that a particular product uses the prefix.
The assignment covers the first 24 bits of a 48-bit address, leaving 24 suffix bits, or 16,777,216 possible suffix values. That is a mathematical address space, not a count of devices or shipments. For this exact prefix, the first octet is E8 (11101000): its Group bit is 0 and its Local bit is 0. Changing either bit produces a different prefix and no longer matches this exact assignment.
For identification, compare the first three octets of the captured MAC address with E8:48:1F. A match supports the IEEE registry attribution; it does not establish where the address was deployed, how common it is, or whether the current device or its software is safe. The supplied records provide no product catalog or device mapping for this assignment.
