A. B. C. D.


The correct answer is C. Teredo.

Teredo is an IPv6 tunneling protocol that allows IPv6 packets to be transmitted over IPv4 networks. It is designed for use with NAT devices that may be blocking IPv6 traffic. Teredo uses IPv4 UDP packets to encapsulate IPv6 packets and tunnel them through an IPv4 network.

Teredo does not require dedicated gateway tunnels, which makes it a cost-effective solution for small networks that need to support IPv6. Additionally, Teredo can pass through existing IPv4 NAT gateways without requiring any modifications to the network infrastructure.

Teredo uses a Teredo server to facilitate the tunneling process. The Teredo client sends traffic to the Teredo server, which forwards the traffic to its destination. The Teredo server also provides the Teredo client with a unique IPv6 address that can be used to communicate with other IPv6-enabled hosts on the Internet.

One potential drawback of Teredo is that it can introduce additional latency and overhead to network traffic. However, for networks that require IPv6 connectivity but cannot easily upgrade their infrastructure, Teredo can be a useful solution.

To summarize, Teredo is an IPv6 host-enable tunneling technique that uses IPv4 UDP, does not require dedicated gateway tunnels, and can pass through existing IPv4 NAT gateways.
