The IPv6 address 2002:ab10:beef::/48 is a special address range reserved for various transition mechanisms from IPv4 to IPv6. Let's examine the given statements to identify the true ones:

A. The embedded IPv4 address can be globally routed: True This statement is true. The address range 2002::/16 is specifically reserved for 6to4 tunneling, which allows IPv6 packets to be encapsulated within IPv4 packets for transmission over an IPv4 network. The embedded IPv4 address within the address 2002:ab10:beef::/48 can be globally routed using IPv4 infrastructure.

B. It is used for an ISATAP tunnel: False The address range 2002::/16 is not used for ISATAP tunneling. ISATAP uses the address range FEC0::/10.

C. The embedded IPv4 address is an RFC 1918 address: False The statement is false because the address range 2002::/16 is not reserved for private use, and the embedded IPv4 address can be globally routed.

D. The MAC address 20:02:b0:10:be:ef is embedded into the IPv6 address: False This statement is false. A MAC address is not embedded into an IPv6 address. Instead, the interface identifier portion of the IPv6 address is typically derived from the MAC address using a specific algorithm.

E. It is used for a 6to4 tunnel: True This statement is true. The address range 2002::/16 is specifically reserved for 6to4 tunneling, which allows IPv6 packets to be encapsulated within IPv4 packets for transmission over an IPv4 network. The address 2002:ab10:beef::/48 falls within this range and can be used for 6to4 tunneling.

Therefore, the true statements about the IPv6 address 2002:ab10:beef::/48 are: A. The embedded IPv4 address can be globally routed. E. It is used for a 6to4 tunnel.
