The Address Resolution Protocol(ARP)was developed to enable communication on an Internetwork and perform a required function in IP routing.ARP lies between layers( )of the OSI model,and allows computers to introduce each other across a network prior to communication.APR finds the( )address of a host from its known( )address.Before a device sends a datagram to another device,it looks in its ARP cache to see if there is a MAC address and corresponding IP address for the destination device.If there is no entry,the souree device sends a( )message to every device on the network.Each device compares the IP address to its own.Only the device with the matching IP address replies with a packet containing the MAC address for the device(except in the case of “proxy ARP”).The source device adds the( )device MAC address to its ARP table for future reference.A.1 and 2B.2 and 3C.3 and 4D.4 and 5A.IPB.logicalC.hardwareD.networkA.IPB.physicalC.MACD.virtualA.unicastB.multicastC.broadcastD.point-to-pointA.sourceB.destinationC.gatewayD.proxy

解析
地址解析协议(ARP)的开发是为了在Internet上实现通信并在IP路由中执行必需的功能。ARP位于OSI模型的第2-3层之间,并允许计算机在通信之前通过网络相互引入。APR从已知的IP地址中找到主机的硬件地址。一台设备将数据报发送到另一台设备之前,它会查看其ARP缓存以查看目标设备是否存在MAC地址和相应的IP地址。如果没有条目,源设备将发送广播给网络中的每一台设备。每个设备都将自己的IP地址进行比较。只有具有匹配IP地址的设备才会回复包含该设备MAC地址的数据包(“代理ARP”除外)。然后源设备会添加目标设备MAC地址放入到ARP表以供将来参考。
