Flexible IPv6 Migration Scenarios in the Context of IPv4 Address Shortage
This memo presents a solution to solve IPv4 address shortage and ease IPv4-IPv6 interworking. The document presents a set of incremental steps for the deployment of IPv6 as a means to solve IPv4 address exhaustion. Stateless IPv4/IPv6 address mapping functions are introduced and IPv4-IPv6 interconnection scenarios presented. This memo advocates for a more proactive approach for the deployment of IPv6 into operational networks. This document provides the specification of the solution and deployment scenarios together with IPv6 migrations paths.
