What this means

The IEEE assigned the MA-L block ECB0D2 to EM Microelectronic. 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 EC:B0:D2, it is EM Microelectronic hardware.
