How to find IP address Hyper V instance

I am running Hyper V instances on my Windows box. When I run the PS query on the host: 

get-vm | select-object -ExpandProperty networkadapters , the system returns me the IP address of the (running) Hyper V's. My question is where can I find this data? Is it in the registry? I am asking this because if I make a forensic image of the host, I can not run PowerShell queries. 

I searched the Internet but could not find the answer. Hope somebody can help.
