Which three approaches can be used while migrating from an IPv4 addressing scheme to an IPv6
scheme? (Choose three)
A.
static mapping of IPv4 address to IPv6 addresses
B.
configuring IPv4 tunnels between IPv6 islands
C.
use DHCPv6 to map IPv4 addresses to IPv6 addresses
D.
use proxying and translation (NAT-PT) to translate IPv6 packets into IPv4 packets
E.
configure IPv6 directly
F.
enable dual-stack routing
An IP tunnel is an Internet Protocol (IP) network communications channel between two networks. It is used to transport another network protocol by encapsulation of its packets.Another prominent use is to connect islands of IPv6 installations across the IPv4 Internet.
Static NAT-PT uses static translation rules to map an IPv6 address to an IPv4 address. IPv6 network nodes communicate with IPv4 network nodes using an IPv6 mapping of the IPv4 address that is configured on the NAT-PT device
One technique, called dual stack, involves running IPv4 and IPv6 at the same time. End nodes and routers/switches run both protocols, and if IPv6 communication is possible that is the preferred protocol.
