    Hello friends,

    What inference can be drawn from the statement "we cannot assign network ID and broadcast address to a host".

    In what context is the author talking about?

    Proffy , Author is talking about IP Addressing,
    First
    Network ID cannot be set for host because it identifies the whole network and all the hosts are in it. e.g 192.168.1.0 it is only used for routing purpose.
    Second
    Broadcast address is the address where a host send a message and this message received by all the hosts that are attached to the current network and a specific host is able to reply of this message base on MAC Address.

    subnetting is what you should look into.

    Broadcast address is the address where a host send a message and this message received by all the hosts that are attached to the current network and a specific host is able to reply of this message base on MAC Address.
    .

    See with this definition of a broadcast address, why can't a broadcast address be assigned to a host? In order to send a broadcast message to say 10 nodes, all must have the same broadcast address (say Y). So, I believe this Y need to be assigned to those 10 nodes. Its only then that they will be able to receive the message.

    Also I believe that these 10 nodes may not necessarily belong to the same network.
    What's your take on this matter?

    IP addresses are unique. Assigning same IP address for more than 1 computer leads to IP address conflict.
    Broadcast address is not a common address that is assigned, its rather a group of addresses to which a packet should be forwarded.
    Broadcast in general is limited within a network. Routers don't forward broadcast packets beyond a network.
    I would suggest you to get familiar with concepts of subnetting and IPV4 addressing.
