You can come up with IP addresses but they don't mean much without the packet data associated with it.
If you're a skilled hacker, you can compromise machines in other countries and route your data that way. But I assume they tracked down the original source the packet data came from. There is no way a regular company can get all that data across the entire nation... You'd have to be an intelligence agency (i.e. NSA) or a large network provider in order to have access to that large scope of a data.
If you just want to double check Mary isn't b.s-ing, then arin.net is sufficient to check out where the IP block is assigned to and what country. You can also manually run a traceroute (though I'd do it from an online web service so that you don't leave a trail back to your machine).
You can use https://search.arin.net/ to determine where the IP block is assigned to
Nope. I didnt bother.
