What this means
The IEEE assigned the MA-L block 000AA7 to FEI Electron Optics. 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:A7, it is FEI Electron Optics hardware.
