Protocols And Standards; Ipv6 Basics Configuration Task List - 3Com S7906E Configuration Manual

Dual stack is the most direct transition approach. A network node that supports both IPv4 and IPv6
is called a dual stack node. A dual stack node configured with an IPv4 address and an IPv6
address can forward both IPv4 and IPv6 packets. For an upper layer application supporting both
IPv4 and IPv6, either TCP or UDP can be selected at the transport layer, while IPv6 stack is
preferred at the network layer. Dual stack is suitable for communication between IPv4 nodes or
between IPv6 nodes. It is the basis of all transitions technologies. However, it does not solve the IP
address depletion issue because each dual stack node must have a globally unique IP address.
Tunneling is an encapsulation technology, which utilizes one network protocol to encapsulate
packets of another network protocol and transfer them over the network. For more information
about tunneling, refer to Tunneling Configuration in the IP Services Volume.
Network Address Port Translation – Protocol Translation (NAPT-PT) is usually applied on a device
between IPv4 and IPv6 networks to translate between IPv4 and IPv6 packets, allowing
communication between IPv4 and IPv6 nodes. It performs IP address translation, and according to
different protocols, performs semantic translation, for packets. This technology is only suitable for
communication between pure IPv4 node and pure IPv6 node.
The S7900E series Ethernet switches do not support NAT-PT.
