I have been getting a lot of requests to share the software that I use in my classes and in the field, so here we go.
This one is called Simple IP Config. Pretty straightforward software where you create different network profiles that you would need in your environment. For example you might need a static IP address to configure equipment for the first time. Or you might need a static IP address for certain networks.
The software is free, has no ads, portable, so nothing to install and lastly, it just plain works well. You can find it here; https://sourceforge.net/projects/simpleipconfig/
Remember that you need to run the software as an administrator and leverage the fact that it uses plain text ini files to further customize.
