What this means
The IEEE assigned the MA-L block B0EC8F to GMX SAS. 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 B0:EC:8F, it is GMX SAS hardware.
