Teredo tunneling is a protocol that:
The correct answer is B. Allows IPv6 connectivity through IPv4 devices. Teredo alleviates this problem by encapsulating IPv6 packets within UDP/IPv4 datagrams, which most NATs can forward properly. Thus, IPv6-aware hosts behind NATs can be used as Teredo tunnel endpoints even when they don't have a dedicated public IPv4 address.
