What this means
The IEEE assigned the MA-L block 00B03B to HiQ Networks. 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:B0:3B, it is HiQ Networks hardware.
