    You can easily do that. While in the form builder, find  the "Preferences" button from the toolbar

     

    In the preferences window, click "Form Limits" tab and Select the "Unique Submission" option that you need, in your case this is Strict Check which controls the IP address.

     

    Here is a guide in details about this matter

    You had to double click on it until a dropdown menu gets enabled:
