What this means
The IEEE assigned the MA-L block 20BFDB to DVL. 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 20:BF:DB, it is DVL hardware.
Frequently Asked Questions
Who owns MAC prefix 20BFDB?
20BFDB is registered to DVL in the IEEE MA-L registry.
