A script that can detect the host type in the Network

Recently, I have been writing a script to automatically detect the host type in the network. The basic function can be used to determine the host operating system type. If the host is in the domain, you can obtain the host hardware and performance parameters and determine whether a network device exists. For an O & M personnel, it is often necessary to get familiar with a strange network as soon as possible. This script is very convenient. If you have better suggestions, thank you! ######################################## ##### Author: lixiaosong #

Example:

1. Save the script to c :\

2. Run powershell to execute ps c: \>. \ test. ps1 10.7.2 # enter the first three digits of the network.

Ps c: \>. \ test. ps1 10.7.2
