192.168.100.160 , 192.168.100.161 到 192.168.100.174, 192.168.100.175
192.168.100.176 , 192.168.100.177 到 192.168.100.190, 192.168.100.191

因为子网掩码:255.255.255.192所以每个子网的IP地址数=256-192=64个
即划分了4个子网分别为:
192.168.168.0-192.168.168.63
192.168.168.64-192.168.168.127
192.168.168.128-192.168.168.191
192.168.168.192-192.168.168.255
IP:192.168.168.188
在子网192.168.168.128-192.168.168.191
但是由于192.168.168.128是网络号,192.168.168.191是广播号
这两个地址不能被分配给主机使用。
所以有效的主机IP范围是192.168.168.129-192.168.168.190
一共62个地址。
