What this means
The IEEE assigned the MA-L block 001FAB to I.S HIGH TECH.INC. 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 00:1F:AB, it is I.S HIGH TECH.INC hardware.
