TRANSITION FROM IPv4 TO IPv6 BASED NETWORKS

摘要

The Internet has become an essential part of people's life. The Internet operates with a system of IP addresses. Each device needs an IP address to connect with the Internet. Till date the world was relying on IPv4, a 20 year old protocol. However, IPv4 only allows for a limited number of IP addresses, which have ran out at the global level in February 2011. Thus a move to IPv6, with 3.4×10~(38) IP addresses is necessary for the functioning of the Internet. This article deals with the IPv4 and IPv6 protocols in brief, followed by the difficulties in transitioning, along with a case sf udy and the various protocols required to implement a smooth transition.
