ALGOSYSTEM Co., Ltd. MAC prefix identification: vendor known, device unknown
Summary
- // what this is
- Algosystem is registered to MAC prefix
00:13:A0in the IEEE OUI database. When a device's MAC address begins with00:13:A0, that block was registered by Algosystem — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A matching prefix indicates the registry assignment only; it does not identify a specific device, deployment, operating system, or security state.
About this vendor.
A MAC address beginning 00:13:A0 matches the IEEE MA-L assignment to ALGOSYSTEM Co., Ltd.; the supplied evidence does not identify a device type or product for this prefix.
This assignment is 24 bits long, leaving 24 bits for suffix values. The possible suffix space is 16,777,216 values; that is a mathematical capacity, not a count of devices, shipments, or observed addresses.
The first octet is 00: its Group bit and Local bit are both zero. Those bits are fixed for an exact literal 00:13:A0 prefix match. Changing either bit changes the prefix, so the fixed assignment does not itself describe variants with those bits changed. RFC 7042 explains the MAC identifier structure and the Group and Local bits.
The IEEE CSV record names the assignee and shows a country indication of JP (Japan). It does not provide an assignment date. A prefix match indicates a registry assignment; by itself, it cannot establish a particular device, operating system, deployment, or security state.
