AIO LCD PC BU / TPV: registered MAC prefix 00:25:AB
Summary
- // what this is
- AIO LCD PC BU / TPV is registered to MAC prefix
00:25:ABin the IEEE OUI database. When a device's MAC address begins with00:25:AB, that block was registered by AIO LCD PC BU / TPV — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact prefix match identifies the MA-L registry assignment only. The 24 suffix bits provide 16,777,216 possible values, not a device or shipment count. Group and Local bits are fixed at zero for this literal prefix; changing either bit yields a different prefix.
About this vendor.
A MAC address beginning 00:25:AB matches the IEEE MA-L assignment to AIO LCD PC BU / TPV; the supplied evidence does not identify a device category for this prefix. The assignment indicates a registry holder, not a particular product, deployed device, or current vendor identity.
This is one 24-bit prefix, leaving 24 bits for suffix values. Its first byte is 00: the Group bit and Local bit are both zero. The exact prefix therefore has those bits fixed; changing either creates a different prefix. The 2^24 possible suffix values are a mathematical address space, not a count of devices or shipments.
For identification, compare the first three octets of the observed address with 00:25:AB. A match supports attribution to this registry assignment only. IEEE CSV records supplied here do not show assignment dates.
