What this means
The IEEE assigned the MA-L block 00210D to SAMSIN INNOTEC. 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 00:21:0D, it is SAMSIN INNOTEC hardware.
