For what it may be worth, a compliant randomized MAC address will have the first bit set to 0 (group/local) and the second bit set to 1 (locally administered) in the first octet. Looking at this in hex, the permitted values for the 2nd character in first octet of the MAC address will be 2 (0010), 6 (0110), A (1010) and E (1110) using most significant to least significant for the bits.

So a randomized MAC address will start with x2:, x6:, xA: or xE;.

Microsoft for some reason insists the first character can't be a 0 but iOS and Android both allow that.
