    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.Sunch addresses are referred to as multicast addresses,and the act of sending a packet from a source to the members of a (71)group is referred to as multicasting. Multicasting done (72) the scope of a single LAN segment is straight forward. 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 (73)multicast group recognize the multicast address and (74)the packet.In this case,only a single copy of the packet is ever transmitted.This technique works because of the (75)nature of a LAN:A transmission from any one station is received by all other stations on the LAN.
