Final answer:

IPv6 multicast addresses do not start with 'FE'; they begin with 'FF'. Multicast addresses enable a single packet to be sent to multiple destinations.

Step-by-step explanation:

The statement that IPv6 multicast addresses always begin with 'FE' is FALSE. Instead, multicast addresses in IPv6 always start with the prefix FF. IPv6 addresses are 128 bits in length and are represented in hexadecimal. A multicast address is a unique type of address used to send a single packet to multiple destinations. By beginning with 'FF', IPv6 ensures that devices on the network can recognize the address as a multicast address and process it accordingly.

FALSE. IPv6 multicast addresses do not always begin with FE. The initial bits of an IPv6 multicast address represent the address type, and for global multicast addresses, the initial bits are FF.

For example, a global multicast address could start with FF3x, where x represents additional address bits. This range is reserved for global multicast addresses by the Internet Engineering Task Force (IETF).

So, in summary, IPv6 multicast addresses do not always begin with FE, but can also begin with FF for global multicast addresses.
