What this means
The IEEE assigned the MA-L block 0023E2 to SEA Signalisation. 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 00:23:E2, it is SEA Signalisation hardware.
