Question:
Which network migration technique encapsulates IPv6 packets inside IPv4 packets to carry them over IPv4 network infrastructures?

• encapsulation
• translation
• dual-stack
• tunneling

Explanation: The tunneling migration technique encapsulates an IPv6 packet inside an IPv4 packet. Encapsulation assembles a message and adds information to each layer in order to transmit the data over the network. Translation is a migration technique that allows IPv6-enabled devices to communicate with IPv4-enabled devices using a translation technique similar to NAT for IPv4. The dual-stack migration technique allows IPv4 and IPv6 protocol stacks to coexist on the same network simultaneously.
