What this means
The IEEE assigned the MA-L block BCD5B6 to d2d technologies. 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 BC:D5:B6, it is d2d technologies hardware.
Frequently Asked Questions
Who owns MAC prefix BCD5B6?
BCD5B6 is registered to d2d technologies in the IEEE MA-L registry.
What does the MA-L registry type mean?
An MA-L assignment, the IEEE's original OUI format, gives the vendor the first three octets and 16,777,216 device addresses under them. d2d technologies's block covers 16,777,216 addresses.
What devices use BCD5B6?
