Acorp Electronics Corp. MAC prefix: device identity unknown
Summary
- // what this is
- Acorp Electronics is registered to MAC prefix
00:08:75in the IEEE OUI database. When a device's MAC address begins with00:08:75, that block was registered by Acorp Electronics — 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, permitting 16,777,216 possible suffix values, not a device or shipment count. For this exact prefix, the first-octet Group bit (01) and Local bit (02) are fixed at zero. Changing either bit yields a different prefix. A match indicates a registry assignment, not a particular device or security state.
About this vendor.
A MAC address beginning with 00:08:75 matches an IEEE MA-L assignment to Acorp Electronics Corp.; the record does not identify a device category or product that uses it. Treat the match as evidence of the registry assignment, not proof of a particular device, operating system, current legal identity, traffic prevalence, or security state.
This is a 24-bit prefix, leaving 24 bits after it in a 48-bit MAC identifier. The arithmetic permits 16,777,216 suffix values; that is a count of possible values, not a count of devices or shipments. In the first octet 00, the Group bit (bit value 01) and Local bit (bit value 02) are both zero. For this exact literal prefix those bits are fixed. Setting either bit changes the prefix and does not describe variation within this assignment.
For identification, compare the first 24 bits of a captured MAC address with 00:08:75. A match establishes the prefix match only. RFC 7042 describes 48-bit MAC identifiers as an initial assigned prefix followed by additional bits, and explains the Group and Local bit conventions. The IEEE CSV record gives Taiwan as the country indication; it provides no assignment date.
