The NAT64/DNS64 Tool Suite for IPv6 Transition

It is clear that there is not enough time to upgrade existing Internet hosts to dual stack before the IPv4 address pool depletes. This implies that the IPv6 transition and co-existence must support interaction between IPv4 nodes and IPv6 nodes. In this article we describe NAT64 and DNS64, a tool suite that provides a way forward in the IPv4-to-IPv6 transition by allowing communication among unmodified IPv6 and IPv4 nodes.The research of Marcelo Bagnulo leading to these results has received funding from the Ministry of Science and Innovation of Spain, under the QUARTET project (TIN2009-13992-C02- 01) and the MEDIANET project (S2009-TIC1468). The work of Alberto García-Martínez is partially supported by BONE (Building the Future Optical Network in Europe), a Network of Excellence funded by the European Commission through the 7th ICT-Framework Program, and by the MEDIANET project (S2009-TIC1468).Publicad
