网络地址转换与子网划分

The Transformation of Network Address and the Division of Subnet

TCP/IP协议是Internet上的基础协议,互联网上计算机相互间的通信依赖于IP地址,而局域网内节点相互通信则使用MAC地址。文章详细地介绍了IP地址、MAC地址的使用原则和子网划分的方法,剖析了地址解析协议ARP和逆地址解析协议RARP的实现过程。

TCP/IP protocol is a basic one on Internet, the communication among computers on Internet depends on IP address, and the communication among the notes within LAN is on the basis of MAC address. This paper introduces in the detail the applying principles of IP address and MAC address and the methods of subnet division, and analyzes the realization course of the address resolution protocol (ARP) and the reverse address resolution protocol (RARP).
