What is the private IP address
Each router has a private IP address, which is only allowed to be used on private networks. The IP does not need to be globally unique because it does not directly access the address. No one can access private IP addresses outside the private network.
The Internet number allocation Agency (IANA) is a global organization for managing IP addresses. It initially defines a IP address called IP version 4 (IPv4). This type is a 32-bit number, usually expressed as four digits separated by points. For example, 192.168.1.1 or 192.168.0.1. Each point must have a value between 0 and 255, which means that the IPv4 system can accommodate about 4 billion unique addresses. This seems to be a lot in the early days of the Internet. But later there will be more.
In these addresses, IANA keeps some digital blocks private. These are:
- 10.0.0.0 - 10.255.255.255
- 172.16.0.0 - 172.31.255.255
- 192.168.0.0 - 192.168.255.255
All these private IP addresses are reserved for private networks. They all have about 17.9 million different addresses, which is why the router's private IP address does not need to be unique. The router then assigns private IP addresses to each device in its network, whether it is a small home network or an enterprise organization. Each device in the network can use this private IP to connect to other devices in the network.
However, private IP addresses cannot access the Internet by themselves. They need to connect via Internet service provider (ISP). They connect the router first and then connect to the larger Internet through routers.
Finding your Private IP Address
- Press Windows-X to open the Power Users menu, and then click Command Prompt.
- Enter ipconfig to display a list of all your computer's connections.
Your private IP address is IPv4 address. This is anyone who can contact your address in your own LAN. You can share documents and transfer files through this address.
