Auditing license reports for unusual machine or IP Address access

I'm checking our license usage via Bentley's website at https://reporting.bentley.com/report/appusagebyday

Some PCs listed in the report are not on our company's domain, so we need to find out more info about these suspicious PCs to figure out why they are using our company's licenses. But the license report isn't showing IP addresses. How can we make the license report show IP address and usernames for these oddball PCs?

Also, should we ignore unusual / external PCs that access our ProjectWise Client licenses, or should we be concerned about that too?
