If you have read some articles about the internet, you might view the term IPv6. It is vital for the future of the internet. However, what does it actually mean and what influences can it make to your network?
Here we will introduce what is an IPv6 address and list its key features. In addition, we explain its difference compared to the IPv4 address and why the IPv6 adoption is slow. If you want to enable it on your devices, we also offer a guideline.
What Is the IPv6 Address?
To better understand this, you could learn that an IP address is the digital address of the devices connected to the internet. Whether it’s a computer or mobile phone, every device will be assigned an IP address to identify and locate each other.
Without an IP address, data exchanged between devices would not be capable of knowing where to go. The IP addresses are generally classified into IPv4 addresses and IPv6 addresses.
In essence, IPv6 is the latest Internet protocol standard, which defines how the information is transmitted. It normally consists of 128 bits and is divided into eight groups, such as 2001:4860:4860::8888 (here we use Google Public DNS IPv6 address as an example).
IPv6 is designed to take the place of the IPv4. However, for some reason, the transition is still far away from completion. We will explain it in the following paragraph.
Why Does IPv6 Aaddresses Matter?
Since IPv4 is widely used, why do its creators still publish IPv6? Here might be the possible reasons.
Enough address space: As we discussed above, all the devices will get a unique IP address. In the future, the amount of available IPv4 addresses will run out gradually. But IPv6 uses 128-bit addresses while IPv4 is 32-bit IP address. It can support for a long time.
Simple header: IPv6 uses a straightforward header format. It effectively simplifies the routing process and reduces time.
Compatible with new technologies: IPv6 can support advanced technologies like 5G and Internet of Things (IoT) devices. And it can still be compatible with the future technological developments.
Efficient routing: It can reduce the routing tables and enhance the transmitting speed.
More secure: The IP Security is built in IPv6, which can encrypt your data and verify your identity.
Use LightningX VPN to Add an Extra Layer to Your IPv6 Address
It will encrypt your data and ensure its access through authorized devices. All your online activities remain invisible to others, even your ISP won’t be able to know your real IP address. LightningX VPN has disguised it into a virtual one, Besides, it can bypass censorship and restrictions.

You can access websites unavailable in your region. Compatible with Windows, macOS, Android, and iOS, LightningX VPN also offers a 7-day free trial. Download it now to get access to streaming services like Dinsey+, Hulu, HBO, and more.
IPv6 VS IPv4: A Simple Comparison
- IPv6 is 128-bits long, it might look like 2001:4860:4860::8844. On the other hand, IPv4 uses 32-bit addresses such as 192.168.5.0.
- IPv4 has nearly 2³² addresses space, it will eventually come to the limits. On the contrary, IPv6 has about 2¹²⁸ sufficient address space. It can perfectly solve the issue of IPv4 address shortages.
- Due to its great amount, IPv6 makes it harder to locate devices which easily attacked.
- IPsec is a built-in feature in IPv6, ensuring the security of your network. For IPv4, it is not essential.
How to Enable the IPv6 Address on Your Network?
On Window10/11
You can go to “Settings” and select “Network & Internet”. In the status section, click “Change adapter options”. For Windows 11 users, you can tap “Advanced Network Settings” and then click “More network adapter options”.
Now you can see your WiFi and ethernet network. Right-click your WiFi and press “Properties”.

In the network window, locate “Internet Protocol Version 6 (TCP/IPv6)”. Just click “Install” and tap OK to confirm the changes.
On Mac
Navigate to “System settings” and click “Network”. Choose “Wi-Fi” and press the details next to your WiFi network. Scroll down to find “Configure IPv6” and tap “manually”. Now you can enter the new IP v6 address.
Moreover, if you want to disable IPv6, please check the following guide.

Challenges of IPv6 Address Transition
Though IPv6 was published in 1998, it still doesn’t completely replace IPv4. Here are the possible reasons why the adoption is so slow.
- Not all the devices are compatible with IPv6.
- Some networks can support IPv6 and IPv4 at the same time.
- It takes strength to manage all the IPv6 addresses.
- IPv6 might require new hardware or other network infrastructure.
- It also takes more costs to train relevant IT staff.
FAQs – IPv6 Address
Q: Is IPv6 better for gaming?
Generally, IPv6 could improve your gaming experience. It is faster than IPv6 and can effectively reduce lag in gaming.
Q: Should I have IPv6 on or off?
It depends on your specific needs. Be aware that some devices and websites are not able to support IPv6. If your network is enough for your daily use, IPv6 is not necessary.
Q: What is my IPv6?
You can directly search it and find the IPv6 test. It can straightforwardly show your IPv6 address. Don’t expose it to unauthorized access or untrusted individuals, it might leak some sensitive information about your privacy. We suggest you use LightningX VPN to change your IP address while connecting to private or public networks.
Q: Is IPv6 a VPN?
No, IPv6 is the new version of the Internet protocol. On the other hand, a VPN is an Internet tool to help you bypass geo-restrictions. But they are not completely unrelated. You can try a VPN that supports IPv6, offering a lightning-fast and stable connection.
Conclusion
Now you already have a fundamental understanding of the IPv6 address. Based on your specific needs, you can choose to use IPv4 or IPv6. Hopefully, this article can solve some problems you might be curious about.
