What this means
The IEEE assigned the MA-L block 000CE2 to Rolls-Royce. 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 00:0C:E2, it is Rolls-Royce hardware.
