We know that there are three types of L2 MAC addresses corresponding to IPv4 according to receiver (Review: http://blog.csdn.net/yygydjkthh/article/details/6751611 ):
1-Unicast (unicast)
The destination address is a transmission method of a single target. The range is not multicast or broadcast addresses.
2-Multicasting)
The high-Byte Low Position of the MAC address is the multicast address, that is, the eighth digit of the second X in the first XX in XX: XX. ex 01: 00: 5E: 01: 01: 01
3-broadcast (broadcast)
All bits of the MAC address are 1, that is, FF: ff.

The L2 MAC address corresponding to IPv6 is classified into only two types by receiver.
1-Unicast (unicast)

Same as IPv4

2-Multicasting)
The first two bytes of the MAC address are 33: 33: XX: xx
