I've been writing a script that automatically detects host types in the network. Basic functions can be used to determine the host operating system type, if the host can get the host hardware parameters and performance parameters, and determine whether there is network equipment. It is often necessary for an operational staff to familiarize themselves with a strange network as soon as possible. So this script is handy, and if you have better advice, thank you!

Examples of how to use:
1 Save the script to C:\
2 run PowerShell to perform PS c:\>. \TEST.PS1 10.7.2 #只需输入网络的前三位
Copy Code code as follows:
PS c:\>. \test.ps1 10.7.2
