What this means
The IEEE assigned the MA-L block D453AF to VIGO System S.A.. 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 D4:53:AF, it is VIGO System S.A. hardware.
