Communication between networked computers requires a system for providing specific addresses to all attached devices. This allows computers to exchange information with connected devices and guarantees that the correct networked computer will receive the requested information. Providing a guaranteed delivery address alleviates flooding the network with spurious data to ensure the delivery of multimedia data to the correct computer.Ipv4 is the current Internet Protocol, which was designed in 1981. This protocol uses a 32 bit address system, which provides approximately 4.2 billion unique addresses. The current growth of devices connected to the Internet is rapidly depleting the number of available network addresses. To help conserve network addresses, devices connected to the Internet through routers are treated as part of a sub-network with special addresses. Network address translation is needed to link the router subnets with the primary network connection.Ipv6 is the next generation Internet Protocol which was formulated in 1996. It uses a 128 bit address system, which will provide a tremendous number of network addresses. ( 2 to the 128th power ) The updated Internet Protocol supports mandatory network security features that include IP encryption and
