ACME LIGHTING MAC prefix: registry identity only
Summary
- // what this is
- ACME Lighting is registered to MAC prefix
28:BA:B9in the IEEE OUI database. When a device's MAC address begins with28:BA:B9, that block was registered by ACME Lighting — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A literal match to 28:BA:B9 has a first-octet Group bit (I/G, low-order bit) of 0 and Local bit (U/L, second-low-order bit) of 0. The first 24 bits are the assigned prefix; 24 suffix bits yield 16,777,216 possible values, not a device or shipment count. Changing either bit changes the prefix and no longer matches this exact assignment. A match indicates registry assignment only.
About this vendor.
A MAC address beginning with 28:BA:B9 matches an IEEE MA-L assignment to ACME LIGHTING; the available evidence does not identify a device or product using it. The assignment establishes a registry name and prefix, not the maker of a particular captured device or its current operator.
This is a 24-bit prefix, leaving 24 bits for suffix values. That permits 16,777,216 possible suffix values, but does not indicate how many addresses have been issued, devices deployed, or products shipped. The exact prefix fixes the first-byte Group bit and Local bit at zero. Addresses with those bits changed do not match this exact prefix.
RFC 7042 explains that 48-bit MAC identifiers can use an initial organizational prefix followed by additional bits, and describes the Group and Local bits. The supplied record contains no supported device category, product catalog, industry, or company website information. No assignment date is shown in the IEEE CSV records.
