The main contribution we make in this paper is that we propose a waypoint service called AVES that can provide high connectivity from IP hosts to IPv6 or reusable-IP hosts without consuming many IP addresses or changing existing IP hosts and IP network routers. AVES is optimized for deployability and can be deployed easily as a 3rd-party network service. We have implemented and deployed a prototype system at CMU, and have received very positive feedbacks from our subscribers. Further information on AVES can be found at https://www.cs.cmu.edu/~eugeneng/research/aves/.
