What this means
The IEEE assigned the MA-L block 00071F to European Systems Integration. 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 00:07:1F, it is European Systems Integration hardware.
