Upgradation in Technology to Use Internet Protocol - Need of the Hour

Abstract

The internet protocol IPv4 was sufficient for years, but as the requirement of large address space is increasing, while address space of IPV4 is finite successor of IPv4 is needed. There are several limitations which are difficult to avoid and complicate such small address space, non-availability of auto-configuration, security factor, and need of new options and in some other cases present a obstacle to, the advance innovations in the field of the Internet. And to satisfy growing and expanded need of network security a new version or a new protocol is need of hour .The result of efforts to overcome this problem was the development of the new IPv6 protocol which enlarges the address space from 32-bits to 128-bits. IPv6 provide a high large address space, better address design and Enable high performance and scalable internet. Due to these improvements, these days IPv6 is very famous and widely used in associations, corporations and Internet Service Providers (ISP).This paper aim to provide a review about transition from IPv4 to IPv6.
