Powershell: How to perform Ping Sweep and Reverse-Lookup on a private network

There is no such thing as the myth of a “perfect” green-field deployment. But in real life most of the times there is a just room/resources (e.g. time and money) for patches of green on a big brown-field.

Starting from the network and I like to create a basic network diagram will outline at glance things that could potentially limit infrastructure growth or expose it to potential risk that we need to mitigate. Designing , re-designing things well or better is based on getting the requirements right and verify that desired targets are met. To speed up this discovery process we use tools to gather the information we need. Continue reading “Powershell: How to perform Ping Sweep and Reverse-Lookup on a private network”
