Aceex Corporation MAC prefix: vendor identity, device unknown
Summary
- // what this is
- Aceex is registered to MAC prefix
00:05:B4in the IEEE OUI database. When a device's MAC address begins with00:05:B4, that block was registered by Aceex — 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, or 16,777,216 possible values. For this exact prefix, the first-byte Group bit and Local bit are both 0; changing either bit produces a different prefix. Possible suffix values do not indicate a device or shipment count. A prefix match identifies the registry assignment only, not a particular device, deployment, current vendor identity, or security state.
About this vendor.
A MAC address beginning 00:05:B4 matches an IEEE MA-L assignment registered to Aceex Corporation; the assignment does not identify a particular device category. The specific device or product associated with a matching address is unknown.
This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. The first octet 00 has Group bit 0 and Local bit 0. For this exact prefix those bits are fixed. A changed bit produces a different prefix, not another address within the assignment. The number of possible suffix values does not establish the number of devices made or shipped.
A matching address indicates the registered prefix only. It does not establish where or how the address is deployed, the current identity of an operator, or a security state. Compare the first three octets to identify this assignment; do not infer a specific device or product from the match.
