Experiences from initial service provider IPv6 network deployments, such as [RFC6219], indicate that successful transition to IPv6 can happen while supporting legacy IPv4 users without a full end-to-end dual-IP-stack deployment. However, due to public IPv4 address exhaustion, this requires an IPv6 technology that supports IPv4 users utilizing shared IPv4 addressing, while also allowing the network operator to optimize their operations around IPv6 network practices. The use of double NAT64 translation-based solutions is an optimal way to address these requirements, especially in combination with stateless translation techniques that minimize operational challenges outlined in [Solutions-4v6].
