What this means
The IEEE assigned the MA-L block EC2F20 to HYUNDAI WIA. 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:2F:20, it is HYUNDAI WIA hardware.
