AKATSUKI ELECTRIC MFG.CO.,LTD. — MAC vendor identification
Summary
- // what this is
- Akatsuki Electric Mfg.Co is registered to MAC prefix
00:0C:F4in the IEEE OUI database. When a device's MAC address begins with00:0C:F4, that block was registered by Akatsuki Electric Mfg.Co — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The exact prefix has Group bit 0 and Local bit 0. The 24-bit matching boundary leaves 24 suffix bits (16,777,216 possible values); this is address-space capacity, not a device or shipment count. A match identifies the registry assignment, not a specific device, product, current identity, deployment, prevalence, or security state.
About this vendor.
A MAC address beginning 00:0C:F4 matches the MA-L assignment to AKATSUKI ELECTRIC MFG.CO.,LTD. The record identifies the registry assignee; it does not establish which device or product sent a captured frame. No device category or product-to-prefix mapping is documented in the supplied records.
The assignment covers a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. This is a mathematical address-space count, not a count of devices, shipments, or observed addresses. For this exact prefix, the first-octet Group bit and Local bit are both zero. Changing either bit changes the prefix and therefore does not match this literal assignment.
RFC 7042 describes the structure of 48-bit MAC identifiers and the meaning of the Group and Local bits. A match supports identifying the IEEE registry assignment only; it cannot establish deployment, traffic prevalence, current vendor identity, or security status. The IEEE CSV record has no assignment date.
