Aerotelecom Co.,Ltd. MAC Prefix: Device Identity Unknown

A MAC address beginning 00:0F:91 identifies an IEEE MA-L registry assignment to Aerotelecom Co.,Ltd.; the available evidence does not identify a device or device category. The assignment is a registry record and does not establish which devices currently use it, whether it appears in network traffic, or any security status.

The prefix matches the first 24 bits of a 48-bit MAC address: 00:0F:91. The remaining 24 bits have 16,777,216 possible values. That is a mathematical range, not a count of devices, shipments, or addresses observed in use.

For this exact prefix, the first-byte Group and Local bits are both zero. Under RFC 7042’s MAC-address guidance, those fixed bit values are consistent with an individual and globally assigned address. Changing either bit produces a different prefix; variation within this assignment occurs in the remaining bits. Use the full address and network context for identification, since a prefix match alone cannot identify a particular device or its operator.
