Yeah the answer to this question was very obvious this are the basics of networking. we all know that the network address and the broadcast address cant be assigned to a host
Network or subnetwork IP address Broadcast address on the network
Network or subnetwork IP address (for example 11.0.0.0/8 or 13.1.0.0/16) and broadcast address (for example 23.2.1.255/24) should never be assignable to hosts. When try to assign these addresses to hosts, you will receive an error message saying that they cant be assignable.
