请问192.168.10.100/25与192.168.10.200/25是否在同一个网域内

鸟哥的一个题

192.168.10.100/25 , ip是class C,Net_ID 占24位,题目要求为25,即Host_ID借1给Net_ID

192 | 168 | 10 | 100

11000000 10100000 00001010 01100100

下面开始计算Network 与boardcast

11000000 10100000 0000101 0|0 | 1100100

----------------------------------------|--|-------------

ip被分成3段,第1段+第2段是Net_Id(25位) ,第3段(7位)是host_Id

计算Network将Host_Id(7位)全部变成0,最后结果是

11000000 10100000 00001010 |0 | 0000000

----------------------------------------|--|-------------

然后转成10进制后的结果就是

192.168.10.0

计算BoardCast将Host_Id全部变成1,最后结果是

11000000 10100000 0000101 0|0 | 1111111

----------------------------------------|--|-------------

然后转成10进制后的结果就是

192.168.10.127

同理计算192.168.10.200的network与boardcast

192 | 168 | 10 | 200

11000000 10100000 00001010 11001000

25位的Net 与 7位的host

11000000 10100000 00001010 1 | 1001000

将7位的host变成0000000

11000000 10100000 00001010 1 | 0000000

转10进制

network = 192.168.10.128

将7位的host变成1111111

11000000 10100000 00001010 1 | 1111111

boardcast = 192.168.10.255

题目结束

解决“出现Unable to retrieve 192.168.0.100/var/www/html/images/install.img错误”

分析:我们必须了解这个错误出现在哪个阶段才能正确找到错误原因,出现这个错误时已经是在开机PXE引导顺利从dhcp server中获得了ip,(或者光盘引导)均正常,而且正常的读取了ks文件,正确的找到了安装源,否则不会提示无法获取install.img文件.一般无法获取某个文件,不是该文件损坏就是网络不通的问题. 解决办法: 1)我们先证明安装源服务器是正常的,我们用其他机器下载install.img文件,使用下面的命令: wget http://192.168.0.100/var/www/h
