Active Tchnology Corporation: MAC prefix identifies an IEEE registry assignment
Summary
- // what this is
- Active Tchnology is registered to MAC prefix
00:0A:2Cin the IEEE OUI database. When a device's MAC address begins with00:0A:2C, that block was registered by Active Tchnology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact match identifies the IEEE registry assignment only. The first byte 00 has Group bit 0 and Local bit 0; changing either bit changes the literal prefix. The 24-bit suffix permits 16,777,216 values, not an actual device or shipment count. No device category or product is explicitly mapped to this prefix.
About this vendor.
A MAC address beginning 00:0A:2C matches an IEEE MA-L assignment to Active Tchnology Corporation. The available evidence does not identify a device class or connect this prefix to a particular product.
The prefix is 24 bits long, leaving 24 bits in a 48-bit address. That allows 16,777,216 possible suffix values; it is a mathematical range, not a count of devices or shipments. An exact match establishes only that the address begins with the assigned prefix.
For this prefix, the first byte is 00: its Group bit and Local bit are both 0. RFC 7042 describes these bits as significant in MAC addresses and notes that the IEEE assignment uses a zero Local bit, with the Group bit unspecified. Here, the exact literal prefix fixes both bits. Changing either bit changes the prefix, so bit variation does not describe addresses matching this exact assignment.
No IEEE assignment date is shown in the supplied CSV record. The record identifies the registrant only; it does not establish deployment, traffic prevalence, current vendor identity, or security status.
