Which IPv6 address block forwards packets to a multicast address rather than a unicast address?
Click on the arrows to vote for the correct answerA. B. C. D.
The answer is D. FF00::/12.
In IPv6, multicast addresses are used to send packets to multiple devices simultaneously. These addresses start with the prefix FF00::/8. The first 8 bits (FF) indicate that the address is a multicast address, while the next 4 bits indicate the scope of the multicast group.
The FF00::/12 address block is reserved for IPv6 multicast addresses with a link-local scope, which means they are used for communication within a single network segment. This includes all addresses that start with FF02::/16, which are link-local multicast addresses.
On the other hand, unicast addresses are used to send packets to a specific device. The IPv6 address blocks for unicast addresses are:
Therefore, the correct answer is D. FF00::/12.
