IP Address in Kali When Running as Virtual Box

Hello everybody,

I just installed Kali as virtual box and tried to hack my Windows 7 from Kali using Adobe Flash Player buffer overflow exploit. But the ip address I see in Kali starts with 10, it is not my real IP address. So when I go to that ip address from Windows in order to open the backdoor nothing happens and session is not started.

Is this normal - when running Kali in virtual box to have internal address starting with 10? And if that's the case how to hack from virtual box as I think real Ip address is needed.
