Creator Form questions

We are trying to implement an application form using Zoho Creator, and have two specific use cases that we need, but haven't been able to figure out yet using Creator. The application form will be deployed publicly, accessible from our public website.

Our needs:

(1) we need to capture the IP address from the client website, and submit it to the zoho database (with a hidden field); and

(2) we need to allow the client to view their application form and print it on success.

Is there any way to do either of these? Also, we are planning on using the new creator API to style the form, so we won't be using the iframe version of the form.

Thanks in advance!
