What this means
The IEEE assigned the MA-L block BC7DD1 to Radio Data Comms. 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 BC:7D:D1, it is Radio Data Comms hardware.
