Teredo tunneling is a protocol that:
A . Translates Internet Protocol version 4 (IPv4) to Internet Protocol version 6 (IPv6).
B . Allows IPv6 connectivity through IPv4 devices.
C . Provides VPN security.
D . Dynamically allocates IPv6 addresses.
Answer: B
Explanation:
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.
