ARP协议是“Address Resolution Protocol”(地址解析协议)的缩写.所谓“地址解析”就是主机在发送帧前将目标网络层地址转换成目标物理地址的过程.在使用TCP/IP协议的以太网中,即完成将IP地址映射到MAC地址的过程——使用ARP协议针对目标设备的IP地址,查询目标设备的MAC地址,以保证通信的顺利进行.
ARP protocol is the abbreviation of “Address Resolution Protocol” (address resolution protocol). The so-called “address resolution” is the host before sending the target network layer address into the target physical address of the process. In the use of TCP / IP protocol Ethernet, that is, the process of mapping the IP address to the MAC address is completed. The ARP protocol is used to query the IP address of the target device and the MAC address of the target device to ensure the smooth communication.
