On an class C IPv4 network, which of these IPs is used for broadcast traffic

On an class C IPv4 network, which of these IPs is used for broadcast traffic

  • 192.168.0.254
  • 192.168.0.0
  • 192.168.0.1
  • 192.168.0.255

EXPLANATION


It is very similar to the network broadcast we just talked about but varies slightly in the sense that its IP broadcast is not set to 255.255.255.255 , but is set to the subnet broadcast address. For example, my home network is a Class C network : 192.168.0.0 with a subnetmask of 255.255.255.0 or, if you like to keep it simple, : 192.168.0.0/24.
This means that the available valid hosts for this network are from 192.168.0.1 to 192.168.0.254. In this Class C network, as in every other network, there are 2 addresses which I can't use. The first one is preserved to identify the network (192.168.0.0) and the second one for the subnet broadcast (192.168.0.255).
