ADVANCED INTEGRATION RESEARCH — MAC prefix identifies a registry assignment
Summary
- // what this is
- Advanced Integration Research is registered to MAC prefix
00:C0:51in the IEEE OUI database. When a device's MAC address begins with00:C0:51, that block was registered by Advanced Integration Research — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The exact 24-bit prefix fixes the first octet as 00, with Group bit 0 and Local bit 0. Matching the full prefix leaves 24 suffix bits, or 16,777,216 possible suffix values; this is not an observed device or shipment count. Either bit changing produces a different prefix.
About this vendor.
A MAC address beginning 00:C0:51 matches an IEEE MA-L assignment registered to ADVANCED INTEGRATION RESEARCH. The record identifies the assignee; it does not identify a particular device, product, deployment, or current company status.
This is a 24-bit prefix in a 48-bit MAC address, leaving 24 bits for the suffix. There are 16,777,216 possible suffix values, a mathematical range rather than a count of devices or shipments. A captured matching address establishes a prefix match only.
For this exact prefix, the first octet is 00: its Group bit and Local bit are both zero. RFC 7042 explains that these bits have special meaning in MAC addresses; changing either bit produces a different prefix and no longer matches this literal assignment. The IEEE CSV record provides no assignment date.
