IEEE 802.3 3.2.3.1 Address designation
A MAC sublayer address is one of two types:
a)Individual Address. The address associated with a particular station on the network.
b)Group Address. A multidestination address, associated with one or more stations on a given network. There are two kinds of multicast addresses:
1)Multicast-Group Address. An address associated by higher-level convention with a group of logically related stations.
2)Broadcast Address. A distinguished, predefined multicast address that always denotes the set of all stations on a given LAN.
All 1’s in the Destination Address field shall be predefined
a) Individual Addressとb)Group AddressはI/Gビットで区別されて、
b)Group Addressをマルチキャストアドレスと使っているが、a) Individual Addressをユニキャストアドレスとは使っていない。
ユニキャストアドレスとの対比で使われるマルチキャストアドレスとは1)Multicast-Group Addressのことで、これには2)Broadcast Addressは含まれない。
したがって、
> 強いて言えばmulticast, including broadcastだ。
