I am running a small exercise where I am sending fake emails to the employees and I just want to check who opened the link. For this I can get the IP using php or other scripts such as - http://l2.io/, http://www.hashemian.com/tools/visitor-IP.htm etc. That is fine but as they are all connected to a router, I am sure that there will be only one single IP if everyone clicks at the link. So I thought of getting private IP's as well so that they can be tracked using the router logs.
In order to get the Private IP, I am using this - How to get client's IP address using javascript only?
Now I want to store that IP into a database when the page loads. As per my knowledge it can be done by using ajax to store the value into a database but How do I put that value into a variable.

//insert IP addresses into the page
