ABB Inc/Totalflow MAC prefix identification
Summary
- // what this is
- ABB Inc/Totalflow is registered to MAC prefix
00:13:86in the IEEE OUI database. When a device's MAC address begins with00:13:86, that block was registered by ABB Inc/Totalflow — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
About this vendor.
A MAC address beginning 00:13:86 matches an IEEE MA-L assignment to ABB Inc/Totalflow. The supplied evidence does not identify a device category or a particular product for this prefix, so it identifies the registry assignment only. It does not establish which device sent a captured frame or whether the address is deployed, common, or safe.
This is one 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical address space, not a count of devices or shipments. For this exact prefix, the first-byte Group and Local bits are both zero. A set Group bit or Local bit changes the prefix and is not a variation within this fixed assignment.
RFC 7042 explains that a 48-bit MAC identifier can have an assigned initial prefix followed by remaining bits, and describes the Group and Local bits. The supplied IEEE records contain no assignment dates.
