What this means
The IEEE assigned the MA-L block DCE578 to Experimental Factory of Scientific Engineering and Special Design Department. 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 DC:E5:78, it is Experimental Factory of Scientific Engineering and Special Design Department hardware.
