摘要：Thecurrent version of Internet Protocol (IPv4) has not been substantially changed in the past 25 years. IPv4 has proven to be robust and easily implemented. In the early stage, the deployment of IPv6 is prepared and begun on the IPv4-based network. In the intermediate stage, IPv4 and IPv6 coexist. In the later stage, IPv6 plays a leading role on the network and the IPv4 network is gradually withdrawing from the market. Meanwhile, researchers put forward many transition mechanisms for different network infrastructures and different evolution stages. In this paper, a detailed study is made on IPv4 along with its different smart saving techniques. Which help in delay of IPv4 to IPv6 shifting delays. Also different addressing schemes are discussed which remains unchanged in future. Along with that limitations of IPv4 is also focused so present IPv4 network infrastructure can be more secured till IPv6 realization. Further the need for IPv6 is discussed along with its header and address formats.
