Power Shell loop for each ip address

Hey so i have a working code(s) that needs to be run on multiple pc's from a text or csv file. By Ip address. Any help would be appreciated. I need to turn these off (wmi / F&P Sharing) to be able to run another ps file to check windows activation. I have a feeling it has to do with the variable $IP but im still in the learning process.

ForEach($IPinGet-Content"input.txt")Invoke-Command{netshadvfirewallfirewallsetrulegroup="windows management instrumentation (wmi)"newenable=yes}
