IPv4 Strategy in 2026: Why Public IP Addresses Have Become a Business Planning Issue

By Tony Chacko

For many years, public IPv4 addresses were simply allocated whenever they were needed. Few organisations gave them much thought.

Today, the situation is very different.

As businesses expand cloud infrastructure, launch digital services, deploy customer platforms and connect more internet-facing systems, public IPv4 addresses have become an increasingly valuable and limited resource.

For many organisations, IPv4 planning is no longer simply a networking exercise—it has become part of wider infrastructure and business planning.

Why Are IPv4 Addresses Still Important?

Although IPv6 has been available for many years, much of today’s global internet continues to rely on IPv4.

Many applications, hosting platforms, firewalls, VPNs, cloud environments and customer-facing services continue to require public IPv4 connectivity.

Most organisations therefore operate dual-stack environments where IPv4 and IPv6 coexist.

This is likely to remain the case for many years to come.

To better understand the ongoing transition from IPv4 to IPv6, the Internet Society’s IPv6 resources provide an excellent overview:

The Supply Challenge

IPv4 uses a finite address space of approximately 4.3 billion addresses.

Regional Internet Registries have now exhausted their pools of freely available IPv4 addresses, meaning organisations typically obtain address space through recognised transfer processes or commercial arrangements between existing resource holders.

Unlike bandwidth or cloud capacity, the supply of IPv4 addresses cannot simply be expanded.

As demand continues to grow, public IPv4 addresses have become valuable operational assets.

Businesses wishing to understand how recognised IPv4 transfers operate within the RIPE region can refer to the RIPE NCC Resource Transfer guidance:

The Question Has Changed

Historically, organisations asked:

“How many IP addresses do we need?”

Today, a more relevant question is:

“What is the most appropriate way to access the IPv4 resources we need?”

The answer increasingly depends upon business requirements rather than technology alone.

Every Business Requirement Is Different

Not every organisation needs to permanently acquire public IPv4 addresses.

Different projects require different approaches.

Examples include:

• Cloud migration projects
• Data centre relocations
• Disaster recovery environments
• Customer onboarding
• Temporary hosting platforms
• Proof of Concept deployments
• Infrastructure staging
• Software testing
• Mergers and acquisitions

Some requirements exist for only a few weeks or months, while others become permanent operational infrastructure.

Understanding the difference can significantly reduce both cost and complexity.

Building an IPv4 Strategy

As part of wider infrastructure planning, organisations should regularly review:

• Current IPv4 utilisation
• Future growth projections
• Cloud migration plans
• Security architecture
• Public-facing applications
• IPv6 readiness
• Long-term address management

Rather than viewing IPv4 as simply an address allocation exercise, many organisations now treat it as part of their overall infrastructure lifecycle planning.

Organisations planning their long-term addressing strategy should also familiarise themselves with the RIPE NCC IPv6 information, which explains how IPv6 adoption continues to evolve alongside IPv4:

A More Flexible Approach

Just as businesses increasingly consume infrastructure, software and cloud platforms as services, organisations are also adopting more flexible approaches to public IPv4 resources.

Depending on operational requirements, options may include:

• Permanent IPv4 transfers
• Temporary IPv4 assignments
• Managed addressing services
• Hybrid IPv4 and IPv6 strategies

The most appropriate solution depends on technical requirements, project duration, commercial considerations and long-term business objectives.

For organisations undertaking cloud migrations, customer deployments, disaster recovery projects or temporary infrastructure expansion, flexible IPv4 assignment models can provide access to the required address space without the need for permanent acquisition.

This allows organisations to align IP resources with project lifecycles while preserving capital and maintaining operational flexibility.

Looking Ahead

IPv6 adoption will continue to grow.

However, IPv4 will remain an essential part of global networking for the foreseeable future.

Organisations that proactively plan how public IP resources are acquired, managed and utilised will be better positioned to support future digital growth while avoiding unnecessary cost and deployment delays.

Conclusion

Public IPv4 addresses are no longer simply technical identifiers.

They have become strategic infrastructure assets that require careful planning and management.

Whether supporting cloud expansion, launching new digital services or modernising enterprise networks, organisations should consider IPv4 planning alongside connectivity, cybersecurity and business continuity as part of a comprehensive digital infrastructure strategy.

As the market continues to evolve, the ability to access IPv4 resources through permanent transfers, temporary assignments or managed services provides organisations with greater flexibility to meet changing business requirements while preparing for the long-term transition to IPv6.

Frequently Asked Questions

What is an IPv4 address?

An IPv4 address is a unique numerical identifier that enables devices and services to communicate over the internet using Internet Protocol Version 4.

Why are IPv4 addresses still important?

Many cloud platforms, business applications, hosting services and network devices continue to rely on IPv4 connectivity, making public IPv4 addresses an important operational resource.

Can businesses still obtain IPv4 addresses?

Yes. While new allocations are no longer generally available, organisations can obtain IPv4 resources through recognised transfer processes or commercial arrangements, depending on their operational requirements.

Is buying IPv4 addresses the only option?

No. Depending on the business requirement, organisations may choose permanent acquisition, temporary assignment or managed addressing services as part of their wider infrastructure strategy.
