![]() ![]() All bits of network ID set to 0 are used to denote a specific host on the local network and are not routed and therefore, aren’t used.All bits of network ID set to 1 are reserved for use as an IP broadcast address and therefore, cannot be used. ![]() The network ID cannot start with 127 because 127 belongs to the class A address and is reserved for internal loopback functions.The network ID is assigned based on the following rules: Hosts that are located on the same physical network are identified by the network ID, as all host on the same physical network is assigned the same network ID. Host ID in which all bits are set to 1 cannot be assigned because this host ID is reserved as a broadcast address to send packets to all the hosts present on that particular network.A host ID in which all bits are set to 0 cannot be assigned because this host ID is used to represent the network ID of the IP address.Within any network, the host ID must be unique to that network.The host ID is assigned based on the following rules: Host IDs are used to identify a host within a network.
