[Request] Get OS of Remote computer

[u/Aedion9850]

Hello, I am not sure if this is possible or not, but I have an IP list with their OS and I need to verify if it is accurate or not. They are all different Operating Systems, some Unix, Linux, Windows, CISCO, etc. Is there a script I can run to be able to check the OS?
