This paper aims to describe the main outputs of the work carried out inside the IST Euro6IX project with particular reference to a new possible architectural Internet Exchange model. This model is based on the IPv6 hierarchical and aggregatable routing and addressing model permitting to enhance the IX functionalities by proposing to directly assign addresses to IX customer?s networks. In addition, being an Internet Exchange a focal point where traffic is concentrated, several networks and application services benefit from the fact of being partial or totally offered from an IX (e.g., security, AAA, QoS, multicast, mobility, PKI, DNSSEC or policy provision) that could also facilitate the deployment of IPv6 and their required transition mechanisms.
