子网掩码在网络通信中具有非常重要的作用。通过分析网络测试中常用的Ping命令所反馈的不同结果与子网掩码的关系,判断网络故障原因,进行网络定位,帮助用户深入理解子网掩码。对常见网络故障的分析、排除具有重要意义。
Subnet mask in the network communication has a very important role. By analyzing the relationship between the different results and the subnet mask returned by the ping command commonly used in network testing, the cause of the network failure is determined and network positioning is performed to help users understand the subnet mask. The analysis of common network failure, exclusion is of great significance.
