之前有帮一个用户写过一个操作系统部署部署时下载的脚本,客户当时的需求是根据不同的客户端网段,找指定的服务器下载对应的镜像文件和软件包,当时用户给的客户端网段都是 C段
,由于 WinPE
中 powershell
有部分命令不支持,为了偷懒测试,我就直接用批处理写了个脚本,写得比较粗糙,还请大佬别笑话
脚本主要是判断客户端 IP地址
的前 3 段,再根据客户端的网络段找指定的服务器下载

前段时间用户说现在需求有变动,其它地区的客户端网段是 B段
,如果按照之前的脚本,一个 B段
有几百个 C段
,添加起来费人
听了用户的需求,我明白之前的批处理确实不太好处理这个问题,无奈只好重新研究用 powershell
来解决新的需求
我的想法很简单,由于 B段
都是连续的,我就想着将 IP地址
转换成 十进制
,然后根据范围判断找指定的服务器下载,这应该比判断 IP段
要简单多了吧

$octets = $ip -split '\.' | |

} | |

老实说,虽然这个脚本并没有什么技术含量,但是我觉得还是分享一下吧,我相信并不是所有人都知道 IP地址
是可以通过 十进制
来访问的,我也是以前打 CTF
的时候才接触到,应该算是比较冷门的知识吧
