What this means
The IEEE assigned the MA-L block DCA989 to MACANDC. 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 DC:A9:89, it is MACANDC hardware.
