What is IP Address and Why is it Important?


If you are like most people, you have heard the words "IP address" before, but you might not know what they actually mean. IP addresses are unique identifiers assigned to devices on a network, and they are important for a variety of reasons. In this article, we will define IP addresses, explain why they are important, and walk through how they work.

What is IP Address

1. What is an IP address?

IP address stands for "Internet Protocol address." It is a unique identifier assigned to every device connecting to the internet. Your IP address is how websites track your visits and how you can view WebPages. IP addresses can be public or private. Your public IP address is the one that is visible to the world. Your private IP address is the one digital address always used behind the scenes and is known only to your devices and the websites you visit.

2. How is an IP address assigned?

When you connect to the internet, your computer is assigned a unique IP address. This number is generally used for computers to identify your device and communicate with it. Think of your IP address as a mailing address for your computer. It's how other devices on the internet know where to send information destined for your computer. Just as importantly, your IP address also allows websites to track your location and demographic information. This data is used to target you with ads and content that interests you. Your IP address is therefore a valuable piece of information, and it is important to keep it confidential.

3. What are the different types of IP addresses?

There are two main types of IP addresses- IPv4 and IPv6. The IPv4 is the first version and is currently in use. It consists of 32 bits and can support around 4.3 billion addresses. However, with the rapid growth of the internet and smart devices, this is no longer enough. The IPv6 is the new generation of IP addresses that uses 128 bits. This can support a virtually unlimited number of devices and offers a more secure and efficient network.

Public IP Addresses

Public IP Addresses are assigned to networks connected to the Internet. A public IP address is publicly routable on the Internet and is thus accessible in public. You can access the public IP address of your device by directly connecting to the device via Ethernet or USB or another method. The Internet IP (Internet Protocol) address of your device is usually 192.168.x.x.

Private IP Addresses

Many website owners are choosing to use private IP addresses, also called static IP addresses, for their sites. A private IP address allows website visitors to have a more personalized experience, while a static IP address leads to increased security. The owner of a website with a private IP address can associate their IP address with a website's domain name, creating greater brand visibility.

Examples of IP addresses

The Internet Protocol (IP) is a set of rules that define how computers communicate with each other on the Internet. Every device connected to the Internet is assigned a unique address. The most common of these addresses is the Internet Protocol version 4 (IPv4), which identifies computers on the Internet using 4 sets of numbers, known as “octets.” IPv4 addresses can be broken down into four sets of numbers, known as “octets,” that are separated by dots. The octets can be separated into groups of 1-4, with 4 being the “network address” and 2, 3, and 4 being known as the “host address.” IPv4 addresses range from 0 to 255. Each network address represents a range of hosts.

How IP address helps

If you are wondering why your IP address is 169.254.x.x, you need to know that IP address helps. IP addresses are numbers used to identify devices and internet networks. For example, if you wanted to connect to the internet, you would type the IP address of a website into the browser of your computer. An internet provider assigns each device an IP address. An IP address is made up of four groups of three numbers. The first number is between 0 and 255, the second between 0 and 255, the third between 0 and 255, and the last between 0 and 255.

4. Why is an IP address important?

An IP address is important because it is the key to communication between devices on a network. Without an IP address, devices would be unable to find each other or transfer data. IP addresses are also used for security purposes, such as to prevent unauthorized access to a network. Additionally, IP addresses are used to track the activity on the internet and help enforce copyright laws. Therefore, while an IP address might not seem like a big deal, it is actually very important to the functioning of the internet and our daily lives.

5. How can I find my IP address?

To find your IP address, you will need to open up the Command Prompt on your computer. This process is done by typing "cmd" into the search bar on Windows, or by pressing Shift + Command + Spacebar on a Mac. Once the Command Prompt window is open, type "ipconfig" and hit enter. Your IP address is listed under "Ethernet adapter Ethernet." If you are using a wireless connection, your IP address will be under "Wireless LAN adapter Wi-Fi." You can also find your IP address by going to a website like what is My IP Address.


An IP address is an important piece of information that is assigned to every device that is connected to the internet. Every device has a unique IP address that allows identifying and communicating with other devices on the internet. IP addresses are used for a variety of purposes, including identifying and tracking users, authorizing access to websites and online services, and preventing spam and fraud.
