The primary method for transmitting IPv6 traffic over an IPv4 network is tunneling. Tunneling allows IPv6 packets to be encapsulated within IPv4 packets, enabling them to traverse an IPv4 network. This method is specifically designed to facilitate the transition from IPv4 to IPv6, as many existing networks still operate primarily on IPv4.

Tunneling protocols, such as 6to4 and Teredo, utilize this encapsulation process to allow IPv6 packets to reach their destination over an IPv4 infrastructure. By effectively creating a secure pathway for this traffic, tunneling helps maintain communications as organizations gradually adopt IPv6 technology.

While dual stack is a configuration method where a device runs both IPv4 and IPv6 protocols simultaneously, it does not specifically handle the transmission of IPv6 over IPv4 networks in the same way tunneling does. Bridging is typically used for connecting network segments at the data link layer, while subnetting deals with dividing IP address spaces into smaller, manageable parts, which is not directly relevant to the transmission of protocols over differing network layers.

In summary, tunneling is the correct method as it specifically enables the transportation of IPv6 data packets across an IPv4 infrastructure, serving as a bridge during the transition phase of networking
