I’m sure it can’t, especially for foreign IP addresses, VPNs, and a ton of other situations. Even if directly connect to the internet just via your ISP, many countries in Europe (don’t know about US) have laws that would require you to have very good reasons and a court order to get the info you need from the ISP - for a single(!) case.

If it would be possible to simply get the address of all digital visitors, we wouldn’t have to develop all this anti scrape tech and just sue them.
