With IPv6 being increasingly regarded as `ready' for deployment, developers are now addressing the operational issues related to IPv6. One key aspect of this is IPv6 transitioning and more specifically it's management and use within networks. This paper puts forward an IPv6 transitioning architecture that offers a managed approach to the deployment and usage of transitioning mechanisms within medium-to-large scale networks. The aim of this is to provide a simple, robust and secure architecture for IPv6 deployment regardless of the type of network used.
