The future of IPv4: Why demand continues despite IPv6 adoption
IPv4 remains critical in 2026 as enterprises and cloud providers buy, lease, and optimise addresses despite IPv6 growth.

IPv4 remains critical in 2026 as enterprises and cloud providers buy, lease, and optimise addresses despite IPv6 growth.
Context
For more than a decade, IPv6 has been promoted as the long-term answer to IPv4 exhaustion. With its vastly expanded address space, IPv6 was meant to eliminate scarcity from internet addressing altogether. Yet in 2026, IPv4 remains deeply embedded across global networks, cloud platforms and enterprise infrastructure. While IPv6 adoption continues to increase, demand for IPv4 has not faded. Instead, IPv4 addresses have become scarce, tradable resources, increasingly treated as digital capital by enterprises. Service providers, cloud operators and IP management firms such as LARUS demonstrate how IPv4 still plays a central role in real-world infrastructure planning.

Analysis
The question has shifted. It is no longer whether IPv6 will eventually dominate, but whether IPv4 demand will meaningfully decline — and if so, when.

Major content platforms and mobile networks support IPv6, yet critical layers of the internet continue to rely on IPv4. Legacy systems, customer equipment, enterprise firewalls and software stacks often remain IPv4-dependent, making full migration costly and operationally risky. For many organisations, IPv4 offers predictability. Routing behaviour, tooling and troubleshooting practices are well understood, while IPv6 expertise remains inconsistent across regions and teams. This encourages continued IPv4 usage wherever possible.
Key Points
- Despite IPv6 expansion, IPv4 scarcity, legacy systems and market demand mean IPv4 addresses continue to hold operational and economic value.
Actions
Pending intelligence enrichment.
