ABB INDUSTRIAL SYSTEMS AB — vendor identified; device type unknown
Summary
- // what this is
- ABB Industrial Systems AB is registered to MAC prefix
00:00:23in the IEEE OUI database. When a device's MAC address begins with00:00:23, that block was registered by ABB Industrial Systems AB — 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 suffix values. The first-octet Group and Local bits are both 0 for this exact prefix; changing either bit changes the literal prefix. Suffix-space size is not a device or shipment count. A match identifies a registry assignment only.
About this vendor.
A MAC address beginning with 00:00:23 matches an IEEE MA-L assignment to ABB INDUSTRIAL SYSTEMS AB. The registry record does not identify a device category or product, and it does not establish which equipment currently uses the prefix.
This is one 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That number is the size of the suffix space, not a count of devices or shipments. A match establishes the registered prefix only; it cannot identify a specific device, operating system, present-day vendor identity, or security state.
The first octet 00 has Group bit 0 and Local bit 0. For this exact prefix those bits are fixed; changing either produces a different prefix. To check an address, compare its first 24 bits with 00:00:23, while accounting for any locally administered or group address bit changes that would make it a different literal prefix.
