Which two statements about IPv6 address 2002:ab10:beef::/48 are true?(choose two)
A. The embedded IPv4 address can be globally routed.
B. It is used for an ISATAP tunnel
C. The embedded IPv4 address is an RFC 1918 address
D. The MAC address 20:02:b0:10:be:ef is embedded into the IPv6 address
E. It is used for a 6to4 tunnel
It was correct with A and E
The answer is correct :
Any IPv6 address that begins with the 2002::/16 prefix is known as a 6to4 address. A 6to4 gateway adds its IPv4 address to this 2002::/16, creating a unique /48 prefix (because an IPv4 consists of 32 bits).
For example: In the IPv6 address 2002:ab10:beef::/48, “ab10:beef” is equivalent to 171.16.190.239 (convert “ab” in hexadecimal to “171” in decimal; “10” in hexadecimal to “16” in decimal…). Therefore the corresponding IPv4 address can be globally routed.
In this case E is wrong and it will be true if E is :
E:. It is used for 4to6 tunnel
wrong – it is 6to4
