What this means
The IEEE assigned the MA-L block 00049F to Freescale Semiconductor. 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 00:04:9F, it is Freescale Semiconductor hardware.
