Private networks work by using a closed network infrastructure that is isolated from the public internet. In a private network, all the devices are connected to a local network (LAN) or a wide area network (WAN) that is accessible only to authorized users. Private networks are used by organizations or individuals who want to have exclusive access to their data, applications or devices.
The following are the key elements of how private networks work:
1. Private IP address range: devices connected to private networks are assigned private IP addresses that are not routable on the public internet. These addresses are reserved and cannot be accessed directly from outside the network.
1. Access control: private networks are secured using various access control measures like firewalls, virtual private networks (VPNs), and authentication mechanisms that restrict access only to authorized users.
1. Routing: private networks use internal routing protocols that manage data traffic between devices within the network. These protocols ensure that data flows efficiently and securely through the network.
1. NAT (Network Address Translation): NAT technology enables a private network to share a single public IP address. This is very useful when multiple devices in the network need to communicate with the internet, as it allows them to use a single IP address.
In summary, private networks are designed to create a secure environment for data, applications and devices by implementing access control measures and using private IP addresses that cannot be accessed from the public internet.
