What this means
The IEEE assigned the MA-L block 0026CF to DEKA R&D. 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 00:26:CF, it is DEKA R&D hardware.
