    If you want to prevent that your form is submitted multiple times from same IP address, you can set unique submissions on a form. Inside of this guide you can find how to do it: 


    You can set Strict Check which controls the IP address.

    If you want to achieve something else, please provide us more details about what you are trying to achieve?
