Suggested Answer: Explanation 🗳️
Dual stack means that devices are able to run IPv4 and IPv6 in parallel. It allows hosts to simultaneously reach IPv4 and IPv6 content, so it offers a very flexible coexistence strategy. For sessions that support IPv6, IPv6 is used on a dual stack endpoint. If both endpoints support Ipv4 only, then IPv4 is used.
Benefits:
✑ Native dual stack does not require any tunneling mechanisms on internal networks
✑ Both IPv4 and IPv6 run independent of each other
✑ Dual stack supports gradual migration of endpoints, networks, and applications.
