What is the difference between a broadcast address and subnet address?
The broadcast address. Each network or subnet has a dedicated broadcast address, through which all users of the network can broadcast. In a broadcast address, all the host bits are set to the binary value 1, so if all host bits are set to the value 0, this is the subnet address. Example: IPv4 address 192.128.64.7/24.
What is directed broadcast and how does it work?
With directed broadcast, all recipients are always addressed within the target network. A combination of the number of the target network and the setting of all host bits to 1 produces the broadcast address in this case. If the destination is not located in its own (sub-) network, a router forwards the data packet.
