What this means
The IEEE assigned the MA-M block 0CEFAF6 to Firmware Design AS. Every network interface they manufacture under this block has a MAC address beginning with these digits, followed by a unique per-device identifier. If a device on your network shows a MAC starting 0C:EF:AF:6, it is Firmware Design AS hardware.
