HCIA学习笔记九:变长子网掩码VLSM

一、等长子网掩码• 等长子网掩码,可以将网络平均分成几个子网。如C类地址192.168.1.0子网掩码借3位作为网络位,则可以将网络分为2^3=8个子网,每个子网的主机总数=2^(8-3)=32,每个子网的可用主机总数=2^(8-3)-2=30,子网掩码长度=24+3=27。•分成的子网如下:子网地址可用的子机地址本网广播192.168.1.0/27192.168.1.1-192.168.1.30192.168.1.31192.168.1.32/27192.168.1.33-192.168.1.62192.168.1.63192.168.1.64/27192.168.1.65-192.168.
