Imagine you're at a large party with dozens of people, and someone calls out your name to hand you a gift. Your name is crucial for identifying you in the crowd.
Similarly, an IP address acts as a unique identifier for computers, smartphones, and other devices, allowing them to recognize and communicate with one another. Without IP addresses, devices on a network would not be able to connect with each other, making communication impossible.
An IP address (Internet Protocol address) is a unique address assigned to a device connected to a network. IP addresses are required for communication between devices in a network.
There are two significant types of IP addresses:
A private IP address is used for communication within a private network. Private IP addresses are not directly accessible from the internet. Examples of private networks include home and office networks.
You can check your private IP address using the ipconfig command.
Your laptop, desktop, smartphone, and smart TV at home may have private IP addresses like:
These devices can communicate with each other without being exposed to the public internet.
Private IP addresses are reserved for use within private networks, such as homes or offices, and are not routable on the public internet. These ranges are defined by the Internet Assigned Numbers Authority (IANA) in RFC 1918.
Here are the private IP ranges:
Class A:
Range: 10.0.0.0 – 10.255.255.255
Typical Use: Large organizations with extensive internal networks.
Class B:
Range: 172.16.0.0 – 172.31.255.255
Typical Use: Medium-sized networks.
Class C:
Range: 192.168.0.0 – 192.168.255.255
Typical Use: Home networks and small offices.
Public IP addresses are unique addresses assigned to devices that connect directly to the internet. These addresses are visible on the internet and can be accessed from anywhere across the globe.
Internet Service Providers (ISPs) provide public IP addresses, which are critical for devices or servers that need to be accessible over the internet.
Your ISP might assign you a public IP address like 203.0.113.42. You can check which public IP address is assigned to you by going to Google and searching "What is my IP address?"
When you visit a website like www.amazon.com, your public IP address is used to communicate with the Amazon server on the internet.
A public IP address range consists of IP addresses that are not used in the private IP address range or reserved range.
Examples:
Understanding the difference between private and public IP addresses is one of the basic and important concepts in networking.
A private IP address is used for communication inside your home or office network, while a public IP address is used for communication across the internet.

An IP address is a unique address required for communication between devices in a network.
A private IP address is used for communication within a home or office network. These IP addresses cannot communicate directly over the public internet.
A public IP address is used for communication across the internet. It is globally unique and is usually provided by an ISP.
