In which integration method is an IPv6 packet encapsulated within an IPv4 protocol?

The correct answer is D. tunneling. Tunneling is the integration method where an IPv6 packet is wrapped inside an IPv4 packet header, allowing IPv6 traffic to traverse IPv4-only network segments. The IPv4 network treats the encapsulated IPv6 packet as payload. Common tunneling mechanisms include 6to4, ISATAP, and T

Explanation

Tunneling is the integration method where an IPv6 packet is wrapped inside an IPv4 packet header, allowing IPv6 traffic to traverse IPv4-only network segments. The IPv4 network treats the encapsulated IPv6 packet as payload. Common tunneling mechanisms include 6to4, ISATAP, and Teredo. Dual-stack (A) runs both IPv4 and IPv6 natively on the same device without encapsulation. NAT-PT (E) translates between IPv4 and IPv6 addresses at the network boundary rather than encapsulating. Dot1q (C) is an Ethernet VLAN tagging standard unrelated to IPv6 migration. Proxy (B) is a general forwarding mechanism, not an IPv6-in-IPv4 encapsulation method.
