[多选题] Which two statements are true about using IPv4 and IPv6 simultaneously on a network segment? （）

A、IPv6 allows a host to create its own IPv6 address that will allow it to communicate to other devices on a network configured via DHCP. IPv4 does not provide a similar capability for hosts. B、IPv6 provides for more host IP addresses but IPv4 provides for more network addresses. C、Hosts can be configured to receive both IPv4 and IPv6 addresses via DHCP. D、Host configuration options for IPv4 can be either statically assigned or assigned via DHCP.Host configuration options for IPv6 can be statically assigned only. E、IPv4 and IPv6 addresses c an be simultaneously assigned to a host but not to a router interface.

[单选题] Which of the following solutions will encapsulate IPv6 packets with IPv4 headers？（）

A、Create an IPv4 tunnel and assign the tunnel IPv6 addresses B、Create IPv4 interfaces on both ends of the network， and use either static routes or a routingprocess to direct IPv6 packets through those interfaces C、IPv6 packets cannot be encapsulated with IPv4 headers because the addresses are notcompatible D、Create IFV6 interfaces on both ends of the network， and use static routes to point the IPv4address to those interfaces E、Use an IPv6 routing protocol like OSPFv3 and assign IPv4 packets to that process F、Create an IPv4 tunnel and use the tunnel mode ipv6ip command
