Adding domains and IP - CLI Script

Hi,

In the case that a website suggest a list of domains and/or IP addresses, I would like to know how to make a CLI script to either create a new group or add members to a new group. I know the indentation is important.

Example: https://learn.microsoft.com/en-us/mem/intune/fundamentals/intune-endpoints?tabs=north-america

I was adding things manually but now there's so much that I'm looking into upload CLI scripts.

Thank you for your time.
