ipv4 vs ipv6 address

With the dawn of the internet age, IPv4 address space ran out. The world needed a new addressing system and fortunately for us, IPv6 was born. 

So why use IPv6? There are plenty of good reasons! For example, IPv6 allows for more than 4 billion addresses (compared to 2^32 – 1 for IPv4), meaning that there is plenty of room for growth. Additionally, because IPv6 uses 128-bit addresses, it can support more devices on a single network than IPv4 can. And finally, since IP addresses can be shared among multiple devices on a network, using IPv6 also helps to conserve network resources.

So if you’re looking to upgrade your networking infrastructure or simply want to be ready for the future, give IPv6 a try!

IPv4 vs IPv6: What’s the Difference?

There are many differences between IPv4 and IPv6, the two most important of which are address space and protocol support. 

IPv4 has a 32-bit address space, while IPv6 has a 128-bit address space. This means that IPv6 can support more than 4 billion addresses. 

IPv4 is mainly used on LANs and intranets, while IPv6 is deployed more widely across the Internet. Currently, only about 30% of Internet traffic is using IPv6. 

One reason for this slow adoption rate is the lack of native IPv6 applications. However, this is starting to change as developers start to create more applications that take advantage of the extended addressing space and unique features of IPv6.

IPv4 Limitations Applied to the Latest Generation of Networks

In the early days of the internet, IPv4 addresses were in high demand. For example, back in 1995, when the first version of the World Wide Web was created, only 4.3 billion IPv4 addresses were available. As time went on and more people became online, the need for more IPv4 addresses skyrocketed. This is because each device on a network needs an individual IP address.

However, as computers and devices became more interconnected and used more applications that required multiple connections (such as streaming video), the number of IPv4 addresses quickly ran out. In 2007, it was estimated that there were only about 3.5 billion remaining IPv4 addresses available[1]. Things didn’t get much better after that; by 2014, it was predicted that there would be just 2.7 billion remaining IPv4 addresses[2].

Transitioning to IPv6: Tips and Tricks

Whether you’re upgrading your home network to IPv6 or just curious about the new protocol, these tips will help you make the transition as smooth as possible. 

  1. Get a solid understanding of IPv6. If you’re just starting out, take our quick quiz to see if you’re ready for IPv6. This guide from Wikihow is a good place to start if you don’t have any experience with IP addresses. 
  2. Test your network and devices on IPv6. One of the best ways to make sure everything is working correctly is to test it on-premise and in your cloud subscriptions. Most ISPs provide tools to do this automatically, so be sure to ask about options before making the switch. 
  3. Make a plan for address space utilization and management.

How to Check if Your Computer is using IPv4 or IPv6

If you’re like most people, you probably don’t think about your computer’s IP address very often. But your computer’s IPv4 or IPv6 address is important—it’s what identifies your computer on the Internet.

IPv4 is the older and less common IP protocol, and IPv6 is the newer and more popular protocol. Most computers still use IPv4, but many websites and other services are designed to work with only IPv6. So if you want to be sure that your computer can connect to websites and services that require an IPv6 address, you need to check whether your computer has an IPv6 address.

To find out whether your computer has an IPv6 address, open the Windows Control Panel (Windows XP: Start > Settings > Control Panel; Windows Vista: Start > Control Panel > Network and Internet).

The Advantages of IPv6 Over IPv4

In this article we are going to take a look at the advantages of using IPv6 over IPv4. First and foremost, IPv6 has more addresses available than IPv4. This means that you can create more robust networks without running out of addresses. Additionally, IPv6 is faster than IPv4 as it uses a different protocol. Finally, devices on an IPv6 network can communicate with each other without any issues.

Should You Switch from IPv4 to IPv6?

IPv4 and IPv6 are two different types of network addresses. You may be wondering if it makes sense to switch from IPv4 to IPv6, or if you should stick with IPv4 for the time being. Here’s a look at the pros and cons of switching to IPv6.

Pros of Switching from IPv4 to IPv6: 

There are many benefits to switching from IPv4 to IPv6. For one, IPv6 provides more addresses than IPv4. With over 340 million possible addresses, that means your site can have more than four times as many hosts as with IPv4. Additionally, because IPV6 addresses are composed of 128 bits, they can support a much larger number of devices and users on the internet.

FAQs Questions

What is the difference between an IPv4 and an IPv6 address?

An IPv4 address is typically 32 bits in length and defines a unique physical location on the internet. An IPv6 address, on the other hand, is 128 bits in length and provides far greater addressing capacity than IPv4. This allows for billions of unique addresses to be provisioned without running out of space. In addition, because IPv6 addresses can be generated automatically using a process known as prefix delegation, they are much easier to manage than traditional IP addresses.

Should I use IPv4 or IPv6?

When you’re choosing a network protocol to use, IPv4 or IPv6, it’s important to keep in mind the following: 

-IPv4 is more commonly used than IPv6. 

-IPv6 offers some advantages over IPv4, including increased bandwidth and the ability to support more devices. 

-There is no one right answer when it comes to which protocol to use – each situation will be different.

Which is faster IPv4 or IPv6?

Many people believe that IPv6 is faster than IPv4, but the truth is that it’s difficult to say for certain which protocol is faster. In general, IPv4 works better on older networks and computers, while IPv6 can support more users and more devices. However, there are a few factors that can affect performance, such as the type of network traffic being handled and the hardware used. So while there may not be a clear winner when it comes to speed, IPv6 is still a very important technology.

Why is IPv6 used instead of IPv4?

The current IPv4 address space is running out, and with it comes the need for a new networking protocol. IPv6 was created as a replacement to IPv4 in order to take advantage of the growing number of devices connected to the internet. IPv6 offers more addresses than IPv4 and supports a larger number of devices. Additionally, IPv6 uses a 128-bit address space which allows for more hosts and more communication links.

What is the main benefit of IPv6?

There are many benefits of upgrading to IPv6, the most obvious being that IPv6 offers more than 4.3 billion unique addresses. Some other advantages of IPv6 include:

-IPv6 is more efficient and can support more traffic than IPv4.

-IPv6 allows devices to communicate with each other over the Internet without having to share a single address.

-IPv6 can be used on both mobile phones and computers, making it better suited for global online communication.


In conclusion,IPv4 and IPv6 have their pros and cons, but ultimately it is up to the individual organisation to decide which address format works best for them. IPv4 has been around for many years, so there may be some legacy applications that still require it. However, IPv6 is quickly becoming the new standard and offers many advantages, such as increased security and global reach.
