As IT Pro you must keep documented all IP Addresses of you Servers and any Hardware that connected in the network.
You know every time what ip address used in your network. So you can avoid conflicts and maybe security issues sometimes.
In small environments it's not so difficult to keep up to date your documentation with all ip addresses
Sometimes need to use Powershell instead of GUI in HYPER-V Host. For users that want to learn more Powershell or for those that has a Server Core installation for the HYPER-V Host.
Don't forget that in some cases maybe want to automate a process with Powershell script
