Reserved IP-address Some IP-addresses are reserved and can not be assigned to individual devices in the network. These are reserved addresses include network address that is used to identify the network and broadcast address used for sending broadcast packets to all devices on the network.

Network address: IP-address with binary zeros in all the host bits reserved for the network address. So, for Class A network IP-address is the address 10.0.0.0 network that is host 10.1.2.3. IP-address 172.16.0.0 is an example of the network address class, while 192.16.1.0 belongs to the class C IP-address used by the router to find a table IP-Routes location of the destination network. Appointed decimal numbers that fill the first two octets in a Class B network address

The last two octets contain zero, as these are designed for 16-bit addressing of hosts and used for end devices connected to the network. In IP-address 172.16.0.0 first two octets reserved for the network address; These octets are never used for addressing addresses connected devices. For example, the network 172.16.0.0 device can have IP-address 172.16.16.1. In this example, 172.16 is part of a network address, and 16.1 - hosts.

Directed broadcast address: To transfer data to all devices used in a particular network broadcast address (Directed Broadcast Address). All hosts bits in the broadcast IP-address filled in binary units
