You can't. If an anonymous user edits or posts, the only info the server has about them is their IP address, which is not a reliable means of identification. The next visitor using that IP address might not be the same person.

Legacy wikis allowed messages to be left on an IP address's message wall, but there was never any way to be sure the intended recipient would still have the same IP address on their next visit.
