There are two versions of IP addresses: IPv4 and IPv6. IPv4 addresses are 32-bit numbers and are more commonly used, while IPv6 addresses are 128-bit numbers and are slowly being adopted. IPv4 addresses are written in dotted decimal notation, such as 192.168.0.1, while IPv6 addresses use hexadecimal notation with colons, such as 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
How Does an IP Address Work?
Now that we understand what an IP address is and its importance, let’s explore how it works.
Every device connected to the Internet has a unique IP address. When you type a website’s URL into your browser, the request is sent to the website’s server using the IP address.

An IP address is a unique identifier assigned to devices on a network that enables communication with other devices and the internet. There are different types of IP addresses, classified according to their purpose and scope. Understanding the differences between these types is crucial for managing your network and ensuring security.
IP Address Classes
IP addresses are divided into five classes: A, B, C, D, and E. The first three classes (A, B, and C) are commonly used in local area networks (LANs) and the internet, while the last two classes (D and E) are reserved for multicast and experimental purposes, respectively.
| Class | Range | Default Subnet Mask | No. of Networks | No. of Hosts/Network |
|---|---|---|---|---|
| Class A | 1.0.0.0 to 126.0.0.0 | 255.0.0.0 | 128 (2^7) | 16,777,214 (2^24 – 2) |
| Class B | 128.0.0.0 to 191.255.0.0 | 255.255.0.0 | 16,384 (2^14) | 65,534 (2^16 – 2) |
| Class C | 192.0.0.0 to 223.255.255.0 | 255.255.255.0 | 2,097,152 (2^21) | 254 (2^8 – 2) |
| Class D | 224.0.0.0 to 239.255.255.255 | N/A | N/A | N/A |
| Class E | 240.0.0.0 to 255.255.255.255 | N/A | N/A | N/A |
Public IP Address
A public IP address is a globally unique address assigned to a device on a public network, such as the internet. This address is visible to all devices connected to the internet. Public IP addresses are assigned by internet service providers (ISPs) and are limited in number.
F12
Private IP Address
A private IP address is a non-unique address assigned to devices on a private network, such as a home or office network. Private IP addresses are used for internal communication within the network and are not visible to the internet. The most commonly used private IP address ranges are:
- 10.0.0.0 to 10.255.255.255
- 172.16.0.0 to 172.31.255.255
- 192.168.0.0 to 192.168.255.255
Private IP addresses can be reused across different networks, but they cannot be used to access the internet directly. To connect to the internet, devices on a private network must use a public IP address provided by the ISP.
Overall, understanding the types and classes of IP addresses is essential for managing your network and ensuring security. By knowing the differences between public and private IP addresses, you can protect your devices and data from external threats and ensure proper communication within your network.

IP tracking, on the other hand, involves monitoring the activity associated with an IP address, including websites visited, files downloaded, and emails sent. This can be done through various means, including cookies, web bugs, and spyware. While IP tracking can provide valuable insights for businesses and marketers, it can also raise serious privacy concerns.
If you are concerned about your privacy, you may want to use an IP locator or IP tracker to determine if anyone is monitoring your online activity. These tools can provide information about the physical location of an IP address and help you identify potential security threats.
IP Address Geolocation
IP address geolocation can be used to determine the country, city, and even postal code associated with an IP address. This information can be used for a variety of purposes, including targeted advertising, fraud detection, and security.
However, IP address geolocation is not always accurate and can sometimes be spoofed or manipulated. Some VPNs (virtual private networks) and proxy servers can mask the true location of an IP address, making it difficult to pinpoint a user’s actual location.
IP Address Tracking
IP address tracking involves monitoring the activity associated with an IP address, such as websites visited, files downloaded, and emails sent. This can be done using cookies, web bugs, and other tracking technologies.
While IP address tracking can provide valuable insights for businesses and marketers, it can also pose a serious threat to privacy. Hackers and cybercriminals can use IP tracking to gather sensitive data about users, such as login credentials and financial information.
To protect your privacy, you may want to use a VPN or proxy server to mask your IP address and encrypt your online activity. You can also use IP address checker tools to verify the location of an IP address and ensure that your online activity is not being monitored without your consent.
IP Address Formats and Subnets
IP addresses consist of a series of numbers that uniquely identify devices on a network. The current standard is IPv4 addresses, which consist of four sections of up to three digits each, separated by periods. For example, 192.168.0.1 is a common IP address used by routers.
IPv6 addresses are the newer standard and consist of eight sections of up to four hexadecimal digits each, separated by colons. For example, 2001:0db8:85a3:0000:0000:8a2e:0370:7334 is a valid IPv6 address.
Subnetting is a technique used to divide IP addresses into network and host portions. The subnet mask is a series of 1s followed by a series of 0s, indicating which bits in an IP address identify the network and which bits identify the host. For example, a subnet mask of 255.255.255.0 means that the first three sections of an IP address identify the network, while the last section identifies the host.
IP addresses are divided into five classes, from A to E, with Class A including IP addresses from 1.0.0.0 to 127.255.255.255 and Class E reserved for experimental purposes. Classes B and C are commonly used for private networks, while Class D is used for multicasting.
