In the ever-evolving world of internet technology, keeping track of your public IPv6 address is crucial for various networking tasks. For Linux enthusiasts or professionals, knowing how to quickly retrieve this information via the command line is a valuable skill. In this blog post, we’ll walk through the steps to check your public IPv6 IP address from the Linux command line using Bash.

Step 1: Open Your Terminal

The first step is to open the terminal on your Linux machine. You can usually find it in your list of applications, or you can press Ctrl + Alt + T on most distributions to open it directly.

Step 2: Use a Command-Line Tool

There are several command-line tools available for checking your public IPv6 address. One of the simplest and most effective is curl. Curl is a powerful tool used to transfer data from or to a server and is widely used for various network-related tasks.

Step 3: Run the Curl Command

To retrieve your public IPv6 address, run the following command in your terminal:

curl -6

This command tells curl to fetch the content from, a website that returns the IP address of the client making the request. The -6 flag forces curl to use IPv6.

Step 4: Interpret the Output

After running the command, you should see your public IPv6 address displayed in the terminal. It will typically look something like this:


This string of numbers and letters is your unique public IPv6 address.


Checking your public IPv6 IP address using the Linux command line is a quick and efficient process. Whether you’re a system administrator, a developer, or just a Linux enthusiast, knowing how to perform this task is incredibly useful. Remember, while is a reliable source, there are other similar services available. Feel free to experiment with different tools to find the one that best suits your needs.

Happy networking!
