What this means
The IEEE assigned the MA-L block 0000FD to HIGH LEVEL HARDWARE. 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 00:00:FD, it is HIGH LEVEL HARDWARE hardware.
