Deployment of native IPv6 only networks using stateful NAT64/DNS64: Enterprise networks with IPv6 only clients capable of contacting IPv4 Servers

Newly implemented IPv6 only networks are becoming common and these sites have interest to communicate with the whole Internet (IPv4 Servers and the whole IPv6 Internet). In this paper we will describe and show how to implement a reliable mechanism that allow client nodes connected to IPv6 only networks to be able to communicate with all IPv4 Servers using NAT64/DNS64 protocol translation. When stateful NAT64 is used in conjunction with DNS64, no changes are usually required in the IPv6 client or the IPv4 server including the transit networks. We present a testbed to demonstrate and to guide on how to realise a stateful NAT64/DNS64 which is capable of translating unicast packets carrying TCP, UDP, and ICMP traffic
