A broadcast address refers to a special IP address that is used to send a message or packet to all devices on a network. Broadcast addresses are commonly used for network management tasks, such as sending out configuration updates or discovery requests. While the broadcast address in IPv4 is typically the last address in the network range, in IPv6, it is replaced with a multicast address to allow a message or a packet to be sent to a specific group of devices.
While broadcast addresses offer many benefits, they can cause network congestion, increase security risks, and result in network performance issues. This is why they should only be used when necessary.
