IPv6 does not have broadcast because it does not have the concept of a broadcast address. IPv6 eliminated the broadcast address because of scalability and security concerns. Instead, IPv6 uses a more efficient form of communication called multicast. Multicast is used to send a single packet to multiple devices on a network at the same time whereas broadcast sends a packet to all connected devices. Additionally, IPv6 nodes are able to perform neighbor discovery without broadcast by using multicast packets.
