title: How to access private ip address
body: <p>I have my laptop that is connected to Internet through my Android mobile which is having its hotspot application running. Now my laptop must have been provided with private ip and my mobile is using a public ip address. I am running a web server on this laptop. Now how can I access this web server from my friends laptop which is not a part of the network ?
  I mean which ip address should I provide private ip of the laptop or the public ip address of my mobile?</p>
