What this means
The IEEE assigned the MA-L block 801D0D to IEEE Registration Authority. 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 80:1D:0D, it is IEEE Registration Authority hardware.
