The ever-increasing popularity of internet and its simultaneous users has forced to the need of IPv6 addresses (with much larger address space) & its urgent usage & implementations. But the implementation .deployment and shifting to IPv6 is rather difficult than expected as it suffers from the various technical challenges that needs to be resolved. This paper focuses on the various IPV6 challenges that the users & organizations have to consider & needs to be sorted out before migrating to IPv6 from IPv4. It includes a detailed study of challenges for migrating to IPV6, and an in-depth look of the probable solutions available today.
