A Systematic Review of Transition from IPV4 To IPV6

Abstract

Personal computers (PC) and gadgets have recently become increasingly associated with the Internet. Internet Protocol (IP) has become the driving force for a decade for which devices and organizations tend to rely as a means of communication between hosts or nodes. Thus, it becomes necessary to have a reliable Protocol that will adapt to changes. In a network, an IP address is assigned to each interface that connects to the Internet. Addresses are still assigned using Internet Protocol version 4 (IPv4). IPv4 has demonstrated reliability, compatibility with a wide range of protocols, applications and ease of implementation. IPv4 was supposed to cover all network interfaces, but with a huge increase in the number of devices (computer, mobile phone, tablet, routers, servers and etc.), the reserve of assigned addresses will be exhausted. IPv6 has been deployed to provide new services and to support network growth. This paper compares the key IPv4 and IPv6 specifications, compares the IPv4 and IPv6 header fields and compares the header structure. This article discusses the main problems and difficulties in the transition from IPv4 to IPv6, and describes the methods of translation and tunneling.
