Maybe it is silly, but I wonder if the first 3 hexadecimal values in MAC address represent vendor id (in 01:23:45:ff:ff:ff it is 01:23:45), is there a limit of 16777215 (ff:ff:ff) devices per vendor?

The first 3 values are called an OUI (organizationally unique identifier) and the last 3 values are called NIC (network interface controller) specific. Most big vendors do have more than one OUI, which removes the 2^24 device limit.
