1.Typically, an IP address refers to an individual host on a particular network. IP also accommodates addresses that refer to a group of hosts on one or more networks. Such addresses are referred to as multicast addresses, and the act of sending a packet from a source to the members of a （1）group is referred to as multicasting. Multicasting done （2）the scope of a single LAN segment is straightforward. IEEE 802 and other LAN protocols include provision for MAC-level multicast addresses. A packet with a multicast address is transmitted on a LAN Segment. Those stations that are members of the （3）multicast group recognize the multicast address and （4）the packet. In this case, only a single copy of the packet is ever transmitted.

    空白（5）应选（ ）。

    A. Multicast
    B. unicast
    C. broadcast
    D. multiple unicast

    答案：C
    解析：
    一般来说，一个IP地址对应网络上的一台主机。IP地址还能标识一组或多个网络上的主机组的地址，这种地址叫IP组播地址，把数据源发出的数据包传送给相应组播组成员的过程叫组播。组播在单一局域网段是直接传送的，使用IEEE802以及一些局域网协议如物理层协议。当包含一个组播地址的数据包在局域网段传输时，属于接收数据的组播组中的工作站能够识别这个地址并接收数据包。采用这种方式只需传送一份数据包副本，这是因为局域网是广播通信这个性质：即由一个工作站发出的数据可以被同一局域网内的所有工作站接收。
