What IPv6 really is and why it matters
IPv6, or Internet Protocol version 6, replaces IPv4 to solve the problem of running out of addresses. While IPv4 accommodates around 4.3 billion devices, IPv6 supports roughly 340 undecillion unique IPs—enough for every grain of sand on Earth to have its own number and still plenty left over. This massive space removes the need for address sharing and complex workarounds, and lays the foundation for the web to keep growing into the future. As Lifewire explains, IPv6’s role in supporting a rapidly expanding number of connected devices is vital for keeping pace with global internet use
Why IPv6 has taken so long to spread across the internet
IPv6 was introduced a long time ago. It was designed in the 1990s to replace IPv4, because the older system was running out of addresses. IPv6 could give the internet room to grow. It seemed like a smart move. But even now, more than 20 years later, many networks still use IPv4. The world has not fully moved to IPv6. Google reports that only a little over 40 percent of internet traffic today uses IPv6. This shows the change has been very slow.
One reason is that IPv4 still works. People can go online, send emails, and stream videos with no major problems. So many businesses see no reason to change. It is easier for them to stay with what they already know. Internet service providers also feel the same. They do not want to spend money on new systems unless they have to. If most users do not ask for IPv6, the providers do not feel pressure to offer it.
Jan Žorž, who is Vice President at 6connect Labs, explained this in an interview with Catchpoint. He said the fewer networks that support IPv6, the fewer chances there are to test and monitor it. This creates a cycle. No one moves first, because they are waiting on others. Everyone waits, and the upgrade is delayed again. This is why the internet has stayed on IPv4 for so long, even though IPv6 is ready.
Some networks try to support both IPv4 and IPv6 at the same time. This is called dual stack. It lets people use both systems, but it is not easy to manage. It adds extra costs. It also makes networks more complex. Companies that use this setup often have to deal with more problems. They need more equipment, more staff, and more time. So some of them decide not to use IPv6 at all.
The delay is not caused by a lack of technology. The delay comes from habits, money, and fear of change. Many network engineers know how IPv4 works. They trust it. They do not want to risk breaking something that is already running. This makes it harder for IPv6 to gain ground, even when the benefits are clear.
Better routing under the hood
One of IPv6’s key technical advantages is a simpler header design compared to IPv4. This leaner format allows routers to process data more efficiently, and removes checksum verification on every packet—cutting out unnecessary steps in data handling. Catchpoint confirms that this stripped‑down structure makes routing quicker and more streamlined. In turn, that can mean more consistent connections for end users.
Direct connections, no NAT blockers
IPv4’s shortage of addresses pushed most networks to rely on Network Address Translation (NAT), a workaround that lets many devices share a single public IP. It works, but it adds delays and can break services such as gaming, voice over IP, and smart‑home setups. IPv6 eliminates this need. With globally unique addresses, every device can connect directly to any other, restoring true end‑to‑end reachability. ExpressVPN confirms that IPv6 can be "at least as fast as IPv4, and potentially a bit faster due to reduced NAT overhead and often newer routing infrastructure"
Real‑world performance: marginal gains, meaningful stability
While users won’t see a tenfold increase in download speed, studies show IPv6 can deliver small improvements—around 5 to 10 per cent—in latency and load times. Catchpoint cites tests where no-NAT IPv6 routing led to quicker site access and smoother packet handling . A 2023 study even found average latency reductions of around 10 per cent on IPv6-native networks. That’s just enough to make a difference in fast-paced scenarios like online gaming or video calls. Users on Reddit have noticed their traffic shifting to IPv6 when it’s available, showing how services such as Netflix, Gmail, and Facebook prefer IPv6 paths whenever possible .
Better security built‑in
IPv6 supports IPsec at the protocol level—this wasn’t mandatory in IPv4 but comes standard in IPv6. That makes end‑to‑end encryption easier to implement networks‑wide. The much larger address space also makes scanning for vulnerable devices vastly harder. Catchpoint notes that newcomers may worry about IPv6 security, but most concerns stem from unfamiliarity rather than real risks in the protocol itself . Overall, IPv6 supports a more secure foundation for the internet, assuming good configuration is in place.
A better fit for IoT, mobile and future tech
IPv6 supports stateless address autoconfiguration, meaning devices can self‑assign their own IPs without needing manual setup or DHCP. That makes onboarding Internet‑of‑Things devices or mobile gadgets much easier. Wikipedia points out that campuses like Virginia Tech and Imperial College London have reported 20–80 per cent of their internal traffic over IPv6 since mid-2010s . Technologies like 5G, smart‑city sensors, AI networks and connected vehicles all rely on massive numbers of IP endpoints—IPv6 provides that at scale.
Countries and companies leading the transition
Some places are well ahead. Slovenia’s Go6 Institute helped push its country to top EU readiness levels, according to Catchpoint. Germany and India both exceed 60 per cent adoption of Google's IPv6 traffic, while the US, Brazil and Japan hover near 50 per cent. China has launched the Next‑Generation Internet project, aiming to switch fully to IPv6 by 2030, making IPv6 a default in cloud, IoT and 5G environments. Large organisations—including Google, Facebook, Cisco, AT&T and Comcast—have been pushing IPv6 infrastructure since the first World IPv6 Launch in June 2012, which permanently enabled IPv6 on many major sites.
What could slow the transition
Upgrade costs and complexity remain a barrier. Many consumer routers do not fully support IPv6, and parts of older software stacks can misbehave when native IPv6 is forced. Tunnelling techniques used to bridge old IPv4 networks can introduce extra latency—sometimes doing more harm than good . Low‑end users trying IPv6‑only setups often find compatibility issues with SSH, GitHub and other services unless their ISP has fully rolled out IPv6 support .
How you can enable IPv6 at home
First, check if your ISP supports IPv6 natively. If it does, ensure your router’s firmware is up to date and IPv6 is turned on. Once enabled, most modern devices will auto‑configure themselves. You can test connectivity using sites like test‑ipv6.com. Monitor your network using latency tools to compare IPv4 and IPv6 performance. Catchpoint and LinkedIn posts offer step‑by‑step advice for setting up dual‑stack networks or IPv6‑only configurations with translation back to IPv4 where needed .
What it all means for your browsing experience
For most people using home broadband or mobile connections, switching to IPv6 won’t radically change daily experience. Bandwidth limits remain the same, and–because of Happy Eyeballs mechanisms used by web browsers and apps–IPv4 and IPv6 traffic swap dynamically to the faster route without disruption. The biggest gains come through more reliable connectivity, less interference from NAT devices, and cleaner routing paths. These build a more resilient and future‑proof foundation for emerging tech.
How LARUS helps drive IPv6 adoption in a changing internet
LARUS Limited works closely with internet service providers, hosting companies, and enterprise networks that want to start using IPv6. Many of these organisations still rely on IPv4, because they cannot get enough new addresses. IPv4 addresses are almost gone. This is a real problem for businesses that want to grow or expand into new areas. IPv6 solves this, but not all companies know how to move forward. Some do not have the time or the team to manage the change. LARUS helps by offering IPv6 addresses, helping with planning, and showing companies how to make the move.
The company supports clients in over 180 countries. It is also one of the few service providers that work directly with the Regional Internet Registries (RIRs). This means it can help organisations that are completely new to IPv6 or ones that just need extra resources. LARUS understands that each region has its own rules and network challenges. It offers advice based on real use cases, and this helps companies avoid mistakes. Some businesses want to build large cloud networks or connect many smart devices. Others just want to avoid future risks. LARUS helps with both.
IPv6 is important because the internet keeps growing. More people are online, and more devices need to connect. Phones, cars, and smart machines all use the internet now. IPv4 cannot keep up. LARUS helps companies prepare for this future. It gives them the tools they need so they do not fall behind. It also works with governments and universities that are trying to build stronger digital systems. As more networks turn to IPv6, LARUS supports this change. It makes sure businesses can get the addresses they need, and it helps them use those addresses in the right way.
FAQs
1. Will IPv6 make my internet noticeably faster?
You may see a small speed or latency improvement—often a few per cent—if your ISP and services prioritise IPv6 and remove NAT delays.
2. Is IPv6 more secure than IPv4?
IPv6 includes optional IPsec features and a massive address space that makes scanning more difficult. Still, you must configure it properly to avoid misconfiguration risks .
3. Can my router or devices break from switching?
Older routers or firmware can misbehave. It’s best to update firmware, backup settings, and enable IPv6 gradually to avoid disruptions .
4. Can I force all traffic to use IPv6?
You could set up an IPv6‑only network with translation for IPv4 (like NAT64/DNS64). But expect compatibility issues unless carefully managed .
5. When will IPv4 disappear completely?
IPv4 will still be around for years. Global IPv6 adoption is only around 40 per cent, and IPv4 may remain useful until approximately 2045
