What this means
The IEEE assigned the MA-L block 0014DC to Communication System Design & Manufacturing (CSDM). 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 00:14:DC, it is Communication System Design & Manufacturing (CSDM) hardware.
