IPv4 vs. IPv6: Making the Case for Buying IPv4 Addresses

IPv4 vs. IPv6: Making the Case for Buying IPv4 Addresses

In the realm of networking and the internet, the conversation about IP addresses has evolved from the days of unlimited availability to the modern era of scarcity. Internet Protocol version 4 (IPv4) addresses, once taken for granted, have become a valuable commodity due to their limited supply. With the advent of Internet Protocol version 6 (IPv6) as a successor, there’s an ongoing debate about whether buying IPv4 addresses is still a viable and worthwhile investment. In this blog, we’ll delve into the IPv4 vs. IPv6 dilemma and present a compelling case for why buying IPv4 addresses can still hold significant advantages.


The IPv4 vs. IPv6 Dilemma

IPv4 and IPv6 are two generations of IP addresses, each with distinct characteristics:


  • Limited address space of around 4.3 billion addresses.

  • Ubiquitous and widely supported by devices and infrastructure.

  • Market scarcity due to the exhaustion of available addresses.

  • Established and proven networking technology.



  • Vast address space of approximately 340 undecillion addresses.

  • Designed to meet the demands of the expanding internet, including IoT.

  • Slow adoption due to compatibility issues and infrastructure upgrades.

  • Enhanced security features and simplified network management.


Why Buy IPv4 Addresses?

Compatibility with Legacy Systems: Many existing systems and applications are built to work exclusively with IPv4. This includes both hardware and software components that are challenging or costly to update for IPv6 compatibility. Buying IPv4 addresses ensures that these systems can continue to function smoothly without major disruptions.

  • Transitional Period: While IPv6 is the future, the transition is gradual. During this transitional period, where both IPv4 and IPv6 coexist, IPv4 addresses remain a necessity. Businesses that rely on these addresses for their day-to-day operations can experience continuity by investing in IPv4.

  • Address Scarcity Premium: The scarcity of IPv4 addresses has led to a market where their value has increased significantly. Organizations looking to expand or secure their online presence can leverage this scarcity premium, potentially generating returns on their investment.

  • Immediate Availability: Acquiring IPv4 addresses offers immediate access to a resource that’s still widely used. Unlike IPv6, which requires network reconfigurations and equipment updates, IPv4 addresses can be seamlessly integrated into existing infrastructure.

  • Investment Opportunities: As the demand for IPv4 addresses continues, a secondary market has emerged. Buying IPv4 addresses can be a strategic investment, with opportunities to lease or sell excess addresses when prices appreciate further.

  • Mitigating Transition Costs: Transitioning to IPv6 can be complex and costly. Buying IPv4 addresses can be a pragmatic step to manage these transition costs over time, giving businesses the flexibility to adapt at their own pace.



In the ongoing deliberation between IPv4 and IPv6, the choice to buy IPv4 addresses emerges as a compelling proposition, particularly in today’s interconnected landscape where digital operations are paramount. The alignment with legacy systems, the ongoing transitional requirements, the value driven by scarcity, immediate integration, investment potential, and the ability to manage transition expenses collectively form a robust argument for embracing IPv4 acquisition. While IPv6 holds promise for the future, the tangible benefits and practical advantages of opting to buy IPv4 addresses establish them as a valuable resource, ensuring uninterrupted operations and a solid foothold in the ever-evolving internet realm.
