What are three approaches that are used when migrating from an IPv4 addressing scheme to an IPv6 scheme. (Choose three.)
A. enable dual-stack routing B. configure IPv6 directly C. configure IPv4 tunnels between IPv6 islands D. use proxying and translation to translate IPv6 packets into IPv4 packets E. statically map IPv4 addresses to IPv6 addresses F. use DHCPv6 to map IPv4 addresses to IPv6 addresses
Correct Answer: A, C, D
Explanation:
Several methods are used terms of migration including tunneling, translators, and dual stack. Tunnels are used to carry one protocol inside another, while translators simply translate IPv6 packets into IPv4 packets. Dual stack uses a combination of both native IPv4 and IPv6. With dual stack, devices are able to run IPv4 and IPv6 together and if IPv6 communication is possible that is the preferred protocol. Hosts can simultaneously reach IPv4 and IPv6 content.
