The Future of IPv6 and Cybersecurity

As the technological landscape grows, we’ve become accustomed to hearing about different data breaches almost every other day. This raises serious questions on our cybersecurity practices.

With hundreds of incidents taking place annually, it’s essential to ask the right questions about cybersecurity in general and the steps we should take to improve our digital realm.

Let’s dive into the future of IPv6 and cybersecurity to understand how we can improve our online privacy and security in today’s highly vulnerable era.

Learn more about IPv6.

Moving to modern-day internet protocol addresses (IPv6) is a step in the right direction. The redesigned IP address is an upgrade to the previous version (IPv4), of which addresses are nearly depleted. However, the threat is still there no matter which protocol is introduced.

Future of IPv6

The introduction of IPv6 has made us look at the internet in a new way as it opens our world to a whole lot of new opportunities. IPv6 comes packed with numerous advanced features that enhance a user’s online security. Unlike IPv4, the IPv6 protocol improves your digital footprint against cyberattacks and simplifies network configuration.

Benefits of IPv6

It was introduced as an upgraded version of the IPv4 and has helped people in overcoming the limitations of the previous version. There several benefits of IPv6:

Faster than the previous version

IPv6 is way quicker than IPv4 and has improved the functioning of networks. New internet devices are gradually shifting to IPv6 and will continue to update to this version as it is essential for the development of the network.

More Secure

IPv6 is the most secure internet protocol that has been introduced to date. The increasing cyberattacks need an improved and updated internet protocol so that they can easily tackle these cyberattacks and maintain your online privacy.

IPv6 is protected by the IPsec to ensure that no malware can enter your network. Another advantage of IPsec is that the firewall will never block your connection as the IPsec secures the packet.

Efficient Routing

One of the most significant advantages of IPv6 is that it reduces the size of routing, making routing more efficient and natural. It was difficult to do the same task in IPv4 as the router had to go through the entire process.

In IPv6, routing is handled by the source device that can easily be discovered by the protocol. It enables the unrestricted pathway for the transmission of maximum data.

Pocket Processing

The simplified packet header by the new IPv6 has made pocket processing more accessible than ever before. The fact that IPv6 does not need any checksum for any router hop is what makes it more efficient. The old IPv4 needs to make different checksum for every router hop.

It became possible after getting link-layer technologies that already contains all the checksum and does not require any individual checksum by the pocket.

Simplified network configuration

The best thing about IPv6 is that it offers you a streamlined network configuration that does not need any configuration while connecting to other IPv6 devices.

It is a significant upgrade as IPv4 needed to be manually set up each time you wanted to connect it to other devices. It is a simple process in which a host needs to generate its IP address through the MAC address and then convert it into EUI.

IP address assignment and device numbering will no longer need manual configuration after you start using IPv6.

Directed Data Flows

IPV6 is not limited to the broadcast as it can offer you the better “multicast.” It can save the network bandwidth by sending the packet flows to multiple destinations.

There is another addition in the internet protocol after the IPv6 header got a new field, named Flow Label, that can identify packets belonging to the same flow.

Future of Cybersecurity

Cybersecurity is the process in which the security experts employ measures that protect users, networks, and programs from the cyberattackers who are constantly looking for ways to harm your systems or data.


The entire cybersecurity landscape needs to make a lot of changes in its practice as there are several new types of attacks on networks these days, which can not be protected by old methods.

Just because a system hasn’t reported a data breach does not mean those data breach activities haven’t taken place. It is because there are a lot of upgraded attacks that our systems do not yet understand, protecting from it is something way too far.

Challenges to Cyber Security

Here are the common challenges faced by cybersecurity:

Attacks via Compromised IoT devices

Compromised IoT devices make the most common cyberattacks. It has made it easy for attackers to get all the information they need through a compromised IoT device.

Advancement in AI

Artificial intelligence is the best way to combat digital attacks, but there is a chance that attackers can use it against you as well. Artificial intelligence is all about learning and enhancing itself by past events, but an attacker can easily influence AI for illicit gains.

Cryptocurrency and Blockchain

The popularity of cryptocurrencies and blockchain has made it easier for attackers to compromise your online security. They can attack your network by following one node with multiple activities. 

Why Should We Shift to IPv6?

Experts believe that getting rid of IPv4 as soon as possible is the need of the hour. There are a lot of security issues in using IPv4, and all private and public domains should shift their focus to the advanced IPv6 protocol.

They believe that we have been using IPv4 and IPv6 for different networks, and it can be harmful to us in terms of our online privacy. Every network needs to start using IPv6 so that we can combat these digital effects and make the internet a secure place.


The future of IPv6 and Cybersecurity needs to be conjoined. You can understand it by looking at the data breach figures that happen almost every day.

The attacks that can not even be recognized by our network have forced all the networks to shift to the IPv6 that contains most of the upgrades to combat these attacks. We need to prepare for future attacks before it’s too late.
