What this means
The IEEE assigned the MA-L block E47C1A to mercury corperation. 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 E4:7C:1A, it is mercury corperation hardware.
