Adaptive Micro Systems Inc. — MAC prefix identification

A MAC address beginning 00:0E:12 matches an IEEE MA-L assignment registered to Adaptive Micro Systems Inc.; the supplied evidence does not identify a device category or product for this prefix. The assignment indicates a registry association, not which vendor made a particular device or whether an address is currently deployed.

The prefix fixes the first 24 bits of a 48-bit MAC address, leaving 24 bits (16,777,216 possible suffix values). This is a count of possible suffixes, not a count of devices or shipments. For this literal prefix, the first-byte Group bit is 0 and the Local bit is 0. RFC 7042 describes these bits as the multicast/group and local-address indicators; changing either bit changes the prefix and therefore no longer matches this exact assignment.

To use the match, compare the captured address’s first three octets with 00:0E:12. A match supports identifying the IEEE registry assignment only. It does not establish a specific product, device, operating system, current legal identity, or security state. Assignment dates are unavailable in these IEEE CSV records.
