Question: I want get the ip address of my clients, but i only want to use pure Javascript without another library

I searched in the internet but i can't found a way to do it, I'm a student so, I have no choise, I can use only JavaScript

I found this, but it doesn't work

```
function myIP(){ var vi="uses java to get the users local ip number";
        var yip2=java.net.InetAddress.getLocalHost();   
        var yip=yip2.getHostAddress();
      return yip;
    }

```

Answer: 
No, it's not possible. The table view owns its whole area, and renders cells based on it's internal logic.

You could divide your table view into sections and add a custom cell as a section header or footer, or you could make your cellForRowAtIndexPath serve up a custom type of cell for every 4th row that ONLY contains your full-sized button. That should accomplish your goal.
As Duncan mentioned you could use cellForRowAtIndexPath and place a custom cell type for every 4th row. You can set two types of custom cells in your tableview by setting the `identifier` property. Ex. For every 4th row use the "ad" identifier cell.
