A Correct answer
Explanation

Tunneling is the correct answer because it is specifically the technique of encapsulating IPv6 packets within IPv4 packets. This allows IPv6 traffic to traverse IPv4-only networks during the transition period. Hashing is for data integrity, routing is packet forwarding, and NAT is address translation - none of these encapsulate one protocol inside another.

AI explanation

Tunneling is the technique where IPv6 packets are wrapped inside an IPv4 packet header so they can travel across an IPv4-only network, then unwrapped at the far end. This lets IPv6 'hosts' or networks communicate over existing IPv4 infrastructure during the transition period, unlike NAT (address translation) or routing/hashing which serve different purposes entirely.
