Private IP Address in Computer Networking

Private IP Addresses

Devices connected to a local network are uniquely identified by their private IP addresses. To ensure safe and effective communication within a particular network, they are made to be non-routable on the open internet.

Important Features of Private IP Addresses:

Network Uniqueness: Every device on a local network has a private IP address that is specific to it. This enables direct communication between devices.
Non-Routable on the Public Internet: The public internet cannot route private IP addresses. This aids in shielding gadgets from outside dangers and illegal access.

Defined Ranges: specific ranges of Private IP addresses define by the Internet Assigned Numbers Authority (IANA):

• 10.0.0.0 to 10.255.255.255 (Private IP Address Class A)
• 172.16.0.0 to 172.31.255.255 (Private IP Address Class B)
• 192.168.0.0 to 192.168.255.255 (Private IP Address Class C)

Private IP addresses: Why Use ?

Security: Private IP addresses improve security by shielding devices from the general internet.

Efficiency: Private IP addresses eliminate the need for intricate routing configurations and streamline network administration.

Flexibility: Large-scale networks with multiple devices are made possible by private IP address ranges.
