What this means
The IEEE assigned the MA-L block ACFAA5 to digitron. 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 AC:FA:A5, it is digitron hardware.
