随着网络迅速发展,局域网越来越受欢迎。合理分配IP地址以及科学地使用子网掩码划分子网有助于提高地址空间的实际利用率,进而提高子网的传输带宽。本文主要IP地址和子网掩码的一些基本理论知识以及子网掩码与IP地址的关系进行了分析。
With the rapid development of the network, the LAN is becoming more and more popular. The rational allocation of IP addresses and the use of subnet mask scientifically to divide subnets help to increase the actual utilization of the address space and thereby increase the transmission bandwidth of the subnet. In this paper, some basic theoretical knowledge of the main IP address and subnet mask and the relationship between subnet mask and IP address are analyzed.
