Dotted Quad

Definition of Dotted Quad

A “dotted quad” refers to an IPv4 address, which is a numerical label assigned to devices connected to a computer network. This term is used because an IPv4 address consists of four sets of numbers separated by periods (dots). Each set can range from 0 to 255, and an example of an IPv4 address in dotted quad notation is


The phonetic pronunciation of “Dotted Quad” is:Dotted: /ˈdɒtɪd/Quad: /kwɒd/

Key Takeaways

  1. Dotted Quad is a popular notation used to represent IPv4 addresses, consisting of four decimal numbers separated by periods (dots).
  2. Each decimal number in the Dotted Quad notation represents an octet (8 bits) of the 32-bit IPv4 address, with a range from 0 to 255.
  3. Dotted Quad notation provides an easily readable format for humans to understand and work with IPv4 addresses, as compared to binary or hexadecimal representations.

Importance of Dotted Quad

The term “dotted quad” is important in the realm of technology as it particularly refers to the notation utilized for IPv4 addresses, which are the foundation of internet communications.

Comprising of four decimal numbers ranging from 0 to 255 separated by dots, it enables a simplified and standardized way to represent 32-bit IP addresses.

This convention allows the precise identification of different devices and systems across the internet, thus facilitating crucial aspects like routing, addressing, and general connectivity.

In essence, the dotted quad format plays a vital role in maintaining the smooth functioning and organization of today’s internet infrastructure.


Dotted Quad, often known as IPv4 address, is a system of uniquely identifying devices within a network by assigning them individual, human-readable addresses. As the standard address format for the Internet Protocol (IP) version 4, its primary aim is to serve as a numerical label used for locating and directing traffic towards different devices connected to the internet.

With the rapid development of technology and the need for increased connectivity, this address format has become widely utilized as an essential element for ensuring seamless and organized communication between various devices on a network. While Dotted Quad notation comprises four decimal values separated by periods that represent 32 binary digits, this IP address allocation plays a crucial role in facilitating exchange of information among smartphones, computers, and IoT devices.

Each set of numbers within the range of 0–255 in the address space corresponds to a specific device or entity; thus, making it possible to route data packets accurately through intermediate computers before reaching their destination. Operating in synergy with other networking components like routers, switches, and gateways, Dotted Quad addressing system offers a clear-cut way of identifying and differentiating numerous internet-connected devices— leading to better performance, interconnectivity, and security in the modern digital world.

Examples of Dotted Quad

A dotted quad refers to the representation of an IPv4 (Internet Protocol version 4) address, which is written as four decimal numbers separated by periods (dots). Each number ranges from 0 toIPv4 addresses are used to enable communication between devices over the internet. Here are three real-world examples of the use of dotted quads:Home Network: Most home Wi-Fi networks use private IP addresses which are written as dotted quads. For example, you may see IP addresses like

1,1, or1 assigned to home routers. These addresses allow your home devices, such as smartphones, laptops, and smart TVs, to communicate with each other and to share an internet connection.

Websites: When you type a URL (e.g., into a web browser, it undergoes a process called DNS (Domain Name System) resolution. The URL is translated into an IP address that is represented in the dotted quad format. For example, Google’s public DNS server has the IP address8, and the IP address for could beThe browser uses this IP address to establish a connection and request content from the web server hosting the website.

Network Troubleshooting: Network administrators use dotted quad IP addresses while troubleshooting and managing network connections. Tools such as ‘ping’ and ‘traceroute’ use IPv4 addresses to test network connectivity, identify issues, and determine the data path between two internet-connected devices. For instance, if you experience a connectivity issue with a specific website, you may use ‘ping34’ to check if the issue is related to the website itself or your connection to it.

FAQ – Dotted Quad

What is a Dotted Quad?

A Dotted Quad is a representation of an IP address, which consists of four decimal values separated by periods (dots). Each decimal value can range from 0 to 255, and it indicates the value of one byte in the address. An example would be

Why is it called a Dotted Quad?

It is called a Dotted Quad because it consists of four decimal values separated by periods (dots). The term “quad” refers to the four separated values, which represent each byte in the 32-bit IP address.

What is the purpose of a Dotted Quad?

The primary purpose of a Dotted Quad is to uniquely identify devices within an IP network. It allows routers and other network devices to determine the correct destination for data packets, thus ensuring smooth and efficient communication within the network.

What is the difference between IPv4 and IPv6 Dotted Quads?

IPv4 addresses use the Dotted Quad format, while IPv6 addresses have a different representation. IPv6 addresses consist of eight groups of four hexadecimal digits separated by colons. For example, an IPv6 address may look like 2001:0db8:85a3:0000:0000:8a2e:0370:7334. The primary difference between the two formats is the address space; IPv6 addresses provide a much larger address space than IPv4.

How do I find my device’s Dotted Quad IP address?

For Windows:

  1. Open Command Prompt.
  2. Type “ipconfig” and press Enter.
  3. Find your IP address listed next to “IPv4 Address.”

For macOS:

  1. Open System Preferences and click on Network.
  2. Select your active network connection (e.g., Wi-Fi or Ethernet).
  3. Your IP address will be displayed under “Status.”

For Linux:

  1. Open Terminal.
  2. Type “ifconfig” and press Enter.
  3. Find your IP address listed next to “inet addr” or “inet” under the active network interface.
