In today’s digital age, the internet has become an indispensable part of our daily lives. With the proliferation of smart devices and the Internet of Things (IoT), the demand for efficient and reliable internet connectivity has never been more pressing. At the heart of this connectivity lies the Internet Protocol (IP) address, which serves as the unique identifier for devices on a network. There are two primary types of IP addresses: IPv4 and IPv6. In this article, we will delve into the world of IP addresses and provide a comprehensive guide on how to check if your WiFi is using IPv4 or IPv6.
Understanding IPv4 and IPv6: The Basics
Before we dive into the nitty-gritty of checking your WiFi’s IP address type, it’s essential to understand the fundamental differences between IPv4 and IPv6.
IPv4: The Original Internet Protocol
IPv4, or Internet Protocol version 4, is the original IP address type developed in the 1980s. It uses a 32-bit address space, which allows for approximately 4.3 billion unique IP addresses. IPv4 addresses are typically represented in a dotted decimal notation, consisting of four numbers separated by dots (e.g., 192.168.1.1).
IPv6: The Next-Generation Internet Protocol
IPv6, or Internet Protocol version 6, is the successor to IPv4, designed to address the limitations of the original protocol. IPv6 uses a 128-bit address space, which provides an virtually unlimited number of unique IP addresses. IPv6 addresses are typically represented in a hexadecimal notation, consisting of eight groups of four hexadecimal digits separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
Why Does it Matter Which IP Address Type My WiFi Uses?
You might wonder why it’s essential to know whether your WiFi uses IPv4 or IPv6. Here are a few reasons:
- Compatibility:** Some devices and applications may only support one type of IP address. Knowing which type your WiFi uses ensures that your devices can connect and communicate efficiently.
- Security:** IPv6 has built-in security features, such as mandatory implementation of IPsec, which provides end-to-end encryption and authentication. If your WiFi uses IPv6, you may have an additional layer of security.
- Future-Proofing:** As the internet continues to evolve, IPv6 is becoming increasingly important. Knowing that your WiFi uses IPv6 can give you peace of mind, as you’ll be better prepared for future technological advancements.

What is the difference between IPv4 and IPv6?
IPv4 and IPv6 are two different internet protocols used for communicating data over the internet. The main difference between them is the size of their address spaces. IPv4 uses 32-bit addresses, which can support up to 4.3 billion unique addresses, whereas IPv6 uses 128-bit addresses, which can support virtually unlimited unique addresses. This means that IPv6 has a much larger address space than IPv4, making it more suitable for the growing number of devices connected to the internet.
In addition to the address space, IPv6 also has some other improvements over IPv4, such as improved security and better support for mobile devices. IPv6 is also designed to be more efficient and scalable than IPv4, making it a better choice for large networks and high-speed internet connections.
Why do I need to check if my WiFi is IPv4 or IPv6?
You may need to check if your WiFi is IPv4 or IPv6 for a few reasons. One reason is that some devices and applications may only support one or the other, so you’ll need to know which protocol your WiFi is using to ensure compatibility. Another reason is that some internet service providers (ISPs) may only offer one or the other, so you’ll need to check which protocol your ISP supports.
Additionally, knowing whether your WiFi is IPv4 or IPv6 can also help you troubleshoot connectivity issues. For example, if you’re having trouble connecting to a particular website or service, knowing which protocol your WiFi is using can help you determine if the issue is with your WiFi or with the website or service itself.
How do I check if my WiFi is IPv4 or IPv6 on a Windows computer?
To check if your WiFi is IPv4 or IPv6 on a Windows computer, you can follow these steps: Open the Command Prompt as an administrator, type the command “ipconfig” and press Enter. This will display information about your network connections, including the IP address and protocol being used. Look for the “IPv4 Address” or “IPv6 Address” section to see which protocol your WiFi is using.
Alternatively, you can also check the Network and Sharing Center in the Control Panel. Click on the “Change adapter settings” option, then right-click on your WiFi connection and select “Status”. This will display information about your WiFi connection, including the IP address and protocol being used.
How do I check if my WiFi is IPv4 or IPv6 on a Mac computer?

This will display information about your WiFi connection, including the IP address and protocol being used.
Can I use both IPv4 and IPv6 on my WiFi network?
Yes, it is possible to use both IPv4 and IPv6 on your WiFi network. This is known as dual-stacking, where both protocols are used simultaneously. Many modern routers and devices support dual-stacking, which allows you to use both IPv4 and IPv6 on the same network.
However, it’s worth noting that not all devices and applications support dual-stacking, so you may need to configure your network to use one protocol or the other. Additionally, using both protocols can also increase the complexity of your network, so it’s recommended to use dual-stacking only if necessary.
Will IPv6 replace IPv4 in the future?
IPv6 is designed to eventually replace IPv4, but the transition is expected to take many years. IPv4 is still widely used today, and many devices and applications still only support IPv4. However, as more devices and applications start to support IPv6, the use of IPv4 is expected to decline.
In fact, many organizations and governments have already started to adopt IPv6, and some have even set deadlines for the transition to IPv6. However, it’s unlikely that IPv4 will be completely phased out in the near future, and both protocols will likely coexist for many years to come.
Do I need to upgrade my router to support IPv6?
It depends on your router and your internet service provider (ISP). Many modern routers already support IPv6, but some older routers may not. If your router does not support IPv6, you may need to upgrade to a newer model that does.
Additionally, your ISP may also need to support IPv6 in order for you to use it on your network. If your ISP does not support IPv6, you may need to contact them to see if they have any plans to support it in the future.
