IPv6 packets are converted into IPv4 packets, and vice versa. This describes which co-existence method?

• A. Dual-stack
• B. Tunneling
• C. Translation
• D. NAT64

Answer: (C)

Translating between IPv6 and IPv4 is the translation method. When a packet must move between these two versions, a translator changes the header and related fields so the other side can understand and process it, then does the reverse for the reply. This lets devices using different IP versions communicate without both ends supporting both protocols. It’s different from running dual-stack on a device, where both protocols are present but packets aren’t converted, and from tunneling, which wraps one protocol inside another without converting it to the other protocol’s format. A common real-world example of translation is NAT64, but the scenario described refers to translation in general.
