A2UICT Co.,Ltd. — MAC prefix F8:BE:0D identifies an IEEE registry assignment
Summary
- // what this is
- A2uict is registered to MAC prefix
F8:BE:0Din the IEEE OUI database. When a device's MAC address begins withF8:BE:0D, that block was registered by A2uict — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A matching address is evidence of the IEEE registry assignment only; the assignment does not establish a particular device, deployment, traffic prevalence, or security state.
About this vendor.
A MAC address beginning F8:BE:0D matches an IEEE MA-L assignment registered to A2UICT Co.,Ltd. The supplied evidence does not identify a device category or product that uses this prefix, so the match identifies the registry assignment only.
This 24-bit prefix leaves 24 bits for suffix values, or 16,777,216 possible values. That is a mathematical address space, not a count of devices, shipments, or observed addresses. A captured match alone cannot establish which particular device is involved.
In the first octet F8, the Group bit is 0 and the Local bit is 0. These bit values are fixed for this exact prefix; changing either bit produces a different prefix. RFC 7042 explains the significance of Group and Local bits for MAC identifiers and distinguishes OUIs from longer assigned prefixes.
