The easiest way is to set up a temporary website and upload a server-side script (PHP, Perl, Python, etc) to log all IP addresses that request that script. Send a link only to your target user, and their current IP address will be logged for you. Remember that this IP address may have been re-allocated to a different ISP subscriber even before you got around to viewing the logs.
After this, you can use this to get the information of that user's ISP:
