Which IPv6 prefix range is used to send packets to a group (multicast) address rather than an individual address?

The correct answer is FF00::/8 because this prefix range is specifically reserved for IPv6 multicast addresses. Multicast addresses are used to send a single packet to multiple destinations simultaneously, which is their primary function. Let's look at why the other options are incorrect: 2000::/3 is the global unicast address range, used for publicly routable, unique addresses on the internet. FC00::/7 is the unique local address (ULA) range, which is similar to private IPv4 addresses and is not routable on the global internet. FE80::/10 is the link-local address range, used for communication only on the local network segment and not routable beyond that segment.
