Restrict login to IP addresses app- Per user? or only per server?

Does the “Restrict login to IP addresses” app allow restricting groups, or individual users? Or is it only a per-server restriction?

Really want to be able to restrict certains users (ex: admins) to only be able to log in from trusted networks. If this app does not provide this functionality, is there any way to get it?
