In a large corporate environment, it’s not unusual to have several Azure AD Named Locations (should it be trusted or not). It is even more challenging to keep track of these locations when there are several admins managing the environment. I thought it would be useful to have a script to determine if an IP address is already listed as a Named Location.
This scipt will require AzureAD PowerShell module and an AzureAD account with appropriate privileges to read these locations. It contains a stripped version of the IPInRange tool (link) and basically uses this tool to check if an IP is in one of the Named Location IP ranges.
