IP to be used in the private network

After creating a private network (wired or wireless) for example in an office or at home, you need to define the IP address field to be assigned to different devices (eg, computers, routers, printers, etc.) connected to the network. Since each assigned IP address must be unique, you can not simply assign an IP address to the computer but you must assign an IP address to each device connected to the network.

Following are 3 blocks of private IP address space that is recommended to use in your network. These 3 blocks are reserved by the Internet Assigned Numbers Authority (IANA) for private networks, such as the home network. You can use these blocks of space for your own network without having to worry about conflicting with other IP addresses on the Internet.

10.0.0.0 – 10.255.255.255
172.16.0.0 – 172.31.255.255
192.168.0.0 – 192.168.255.255

After deciding on the block of IP addresses to be used, decide which netmask to use. The netmask defines how many addresses can be assigned in your network. The value is usually used as netmask 255.255.255.0 to have 254 addresses to assign. There is the network address and broadcast address that can not be assigned. The network address it is used to represent the network, mind the broadcast address it is used to communicate with all devices on the network.

Here is an example for assigning network IP addresses.
I have 5 computers and a router in my network. I will assign the address 10.0.0.1 to the router and from 10.0.0.02 to 10.0.0.6 to the computers. I will use the netmask 255.255.255.0, so that I can assign IP addresses from 10.0.0.1 to 10.0.0.254 in the network. The network address will be 10.0.0.0, while the broadcast address it will be 10.0.0.255.
