    To my understanding, you would like to know how you would be able to get the IP Address of the user who submits your form, is that correct? If that is the case, please feel free to follow this link: How-to-See-IP-Addresses-of-Form-Submitters.

    But if you want to detect the IP Address of the Form Submitters so that multiple submission can be prevented you can set your Unique Submissions to Strict Check.

    Loose Check - uses Cookies to prevent multiple submissions, however, one can bypass this by clearing his browser's cookies or by using a different browser to submit your form.

    Strict Check - uses IP address to prevent multiple submissions and this is a very effective solution to prevent spammers.
