Firstly some background. The Internet operates by transferring data in small packets that are independently routed across networks as specified by an international communications protocol known as the Internet Protocol (IP). Each data packet contains two numeric addresses to help it get from the packet's origin and destination devices. Internet Protocol has been publically used since 1981 and its 4th revision (IPv4) was the first to be widely deployed around the world.
However due to the 32-bit address size of IPv4, it is limited to only 4.2Billion unique addresses. This may seem like alot, I’m sure back in 1981 it would of been staggering for the engineers to believe that they could run out of useable addresses within less than 35 years. But as countries expand IT infrastructure to previously remote areas and consumers purchase networkable devcies such as Smart Phones, more and more end-users are appearing with a need to occupy a unique IP address from their ISP.
