Internet Protocol (IP) Address Question:

A private IP Address is the one, which is not recognised on the Internet. This is mostly used to connect different devices locally on a small network or even in huge networks. These devices cannot directly participate on the Internet for the simple reason that they are recognised. This is where devices like Router comes into picture where it translates all the packets from these Private devices into the Public IP Addresses that is being assigned and forwards to the Internet and exactly does the reverse for the incoming packets on the Public IP to give it back to the private devices. This process of translation is called Network Address Translation and the process of forwarding packets from various different networks to different other networks is called Routing.
