Internet Protocol (IP) Address Interview Questions and Answers


What is a Private IP Address?

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.
