acromate, Inc. — MAC prefix identified; device type unknown

A MAC address beginning 2C:A1:57 matches the IEEE MA-L assignment to acromate, Inc.; the available evidence does not identify a device or product using it. The registry record names the company and shows KR in its address field, but provides no assignment date.

This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical range, not a count of devices, shipments, or addresses observed in use. The prefix match indicates a registry assignment; it does not establish a device’s identity, operating system, current vendor identity, traffic prevalence, or security state.

The first byte, 2C (hexadecimal), has Group bit 0 and Local bit 0. Those bits are fixed for an exact 2C:A1:57 prefix match. Changing either bit produces a different prefix; it does not describe variation within this assignment. RFC 7042 explains the significance of these MAC-address bits and prefix assignments.
