The difference here is that when you send a message to the broadcast
address, you are really addressing it to every node within TTL nodes.
That is, every node that receives a message directed to the broadcast
address should process that message as though it were directed to it.
Flooding will have a certain destination address that must be maintained
as it propagates through the network.
