What this means
The IEEE assigned the MA-S block 8C1F64DCA to Porsche engineering. 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 8C:1F:64:DC:A, it is Porsche engineering hardware.
