Broadcast addresses are used to send a message to all devices on a network segment. IPv4 supports broadcast addresses, but IPv6 does not. Instead, IPv6 uses multicast addresses, which are used to send a message to a group of devices that have joined a multicast group. Multicast addresses are more efficient and flexible than broadcast addresses, as they allow the sender to specify the recipients more precisely and avoid unnecessary network traffic. IPv6 also supports anycast addresses, which are used to send a message to the nearest device that provides a specific service. Anycast addresses are useful for load balancing and redundancy.
