What this means
The IEEE assigned the MA-L block C04DF7 to SERELEC. 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 C0:4D:F7, it is SERELEC hardware.
