Which method allows IPv4 and IPv6 to work together without requiring both to be used for a single connection during the migration process?
| A. |
dual-stack method | |
| B. |
6to4 tunneling | |
| C. |
GRE tunneling | |
| D. |
NAT-PT |
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.
