To see the IP history you can use IP lookup that is located on the main menu under tools category.
When you click on IP lookup you can enter the IP address and check its history from your clicks and Rotators. You can see Link data from that IP, Rotator data and pixel data of when the pixel was triggered.
Also it will show the location of that IP from that visitor. You can check if it is a unique click, what Link or Rotator was used, action it triggered, timestamp and so on.
