The Future of Internet: IPv6 Fulfilling the Routing Needs in Internet of Things

In recent years, the world has witnessed drastic change in modes of computing used in different application domains. The computing varies from confined biological sensing to controlling large cities using smart IoTs solutions. Consequently, footprint of devices is increasing at a higher speed. Therefore, for such huge footprint of computing devices it is of the leading importance to diminish the new challenges associated with the devices. Particularly, it demands for comprehensive and futuristic approaches for handling device identification and other related issues. Unfortunately, importance and necessity of public IP address for every device on the planet has not been understood well yet and taken for granted. However, current IPv4 solutions for device identification and management does not seem fit to address problems of this growing global IoT device space. Consequently, there is a dire need for IPv6. At its core, IPv6 is a recognized protocol established since the preceding era. IPv6 upholds the capabilities required for enhancements of network identification, management and data transfer related matters. In this connection, the fundamental objective of this study is to identify key challenges in emergence of devices with a specific and focused approach on IPv6. Moreover, the study shall provide comprehensive analytical overview of IPv4 and IPv6. Furthermore, study shall propose routing advancements required for switching from IPv4 to IPv6 along with backward compatibility.
