Abstract:
The 4rd automatic tunneling mechanism makes IPv4 Residual Deployment
possible via IPv6 networks without maintaining for this per-customer
states in 4rd-capable nodes (reverse of the IPv6 Rapid Deployment of
6rd). To cope with the IPv4 address shortage, customer sites can be
assigned IPv4 addresses with restricted port sets. In some
scenarios, 4rd-capable customer nodes can exchange packets of their
IPv4-only applications via stateful NAT64s that are upgraded to
support 4rd tunnels (in addition to their IP/ICMP translation of
[RFC6145]).
