Accella Technologies Co., Ltd. — MAC prefix identification is vendor-only
Summary
- // what this is
- Accella Technologies is registered to MAC prefix
00:06:BFin the IEEE OUI database. When a device's MAC address begins with00:06:BF, that block was registered by Accella Technologies — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- This 24-bit prefix has 24 suffix bits and 16,777,216 possible suffix values. For the exact literal prefix 00:06:BF, the first-byte Group and Local bits are fixed at 0. A change to either bit is a different prefix. This is a matching interpretation, not a device or shipment count; a match indicates the registry assignment, not an observed device, deployment, or security state.
About this vendor.
A MAC address beginning 00:06:BF matches an IEEE MA-L assignment to Accella Technologies Co., Ltd.; the available evidence does not identify a device category or product for this prefix. A prefix match establishes the registry assignment only. It does not establish which device made a capture, who operates it, or whether the address is currently deployed.
The assignment is 24 bits long, leaving 24 bits for suffix values: 16,777,216 possible values. This is a mathematical address-space count, not a count of devices or shipments. For this exact prefix, the first-byte Group bit and Local bit are both zero. Changing either bit changes the prefix and no longer matches this literal assignment.
RFC 7042 explains that the Group and Local bits have special significance in MAC addresses and that the Group bit distinguishes group from individual identifiers. It also describes MAC identifiers as using an initial OUI or a longer assigned prefix, followed by remaining bits. The IEEE CSV record provides no assignment date.
