Airtech I&C Co., Ltd — MAC prefix identifies an IEEE registry assignment
Summary
- // what this is
- Airtech I&C is registered to MAC prefix
8C:B0:94in the IEEE OUI database. When a device's MAC address begins with8C:B0:94, that block was registered by Airtech I&C — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact
8C:B0:94prefix match identifies the MA-L registry assignment. The literal prefix fixes the Group and Local bits at zero; 24 bits remain for possible suffix values, not an observed device count. A match does not identify a particular device or product.
About this vendor.
A MAC address beginning 8C:B0:94 matches an IEEE MA-L assignment registered to Airtech I&C Co., Ltd; the record does not identify a device category or a specific product. The prefix establishes a registry match only, not the manufacturer of a particular device, its current owner, or its safety status.
This is a 24-bit prefix, leaving 24 bits for possible suffix values: 16,777,216 combinations. That number describes address space, not a count of devices, shipments, or observed network traffic. For an exact literal match, the first-byte Group and Local bits are both fixed at zero. Changing either bit produces a different prefix; variation within this assignment does not change those bits.
RFC 7042 explains that 48-bit MAC identifiers can use an initial OUI or a longer assigned prefix, with remaining bits completing the 48-bit identifier. The supplied IEEE record contains no assignment date. No supplied evidence links this prefix to a device type, product, or current deployment.
