What this means
The IEEE assigned the MA-L block ECBAFE to GIROPTIC. 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 EC:BA:FE, it is GIROPTIC hardware.
