Internet Protocol Version 4 (IPv4) which was developed almost three decades ago is the prevalent protocol version in use today. However, with the unanticipated growth of internet and proliferation of interconnected devices, the authors could soon be facing a scenario where IPv4 addresses are exhausted. While IPv4 addressing allows for billions of addresses, IPv6, the next version of the protocol, has provisions for trillions of addresses which is potentially inexhaustible. Sooner rather than later, migration to IPv6 will be inevitable for all enterprises. This paper from Wipro goes over the challenges of IPv4, benefits of migrating to IPv6, and the approach that enterprises could take to counter the challenges and avoid the pitfalls that they would face during IPv6 migration.
