Hi
I was wondering if it's possible to create a test domain on a VM that I created on my laptop and play around with it including adding other computers to it(other VMs set on the same laptop) with just setting a made up domain name instead of buying
one. I want to mess around and improve my skills but I am not sure if I have to get an official registered domain name for things to work or if making something random up just for the DC setup is enough
