What this means
The IEEE assigned the MA-L block 000A59 to HW server. 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 00:0A:59, it is HW server hardware.
