IPv4 vs. IPv6: Is Now the Right Time to Sell?

The transition from IPv4 to IPv6 has been an ongoing process as the internet continues to expand and the demand for IP addresses grows. While IPv4 addresses are becoming increasingly scarce, the adoption of IPv6 is gradually gaining momentum. This raises an important question for organizations that possess unused IPv4 addresses: Is now the right time to sell? In this blog post, we will explore the considerations surrounding IPv4 and IPv6, helping you make an informed decision about selling your IPv4 addresses.


1. Understanding IPv4 and IPv6

IPv4 (Internet Protocol version 4) has been the dominant protocol for decades, utilizing 32-bit addresses that allow for approximately 4.3 billion unique addresses. In contrast, IPv6 (Internet Protocol version 6) offers 128-bit addresses, providing an enormous pool of unique addresses—over 340 undecillion to be precise. IPv6 is designed to accommodate the growing number of internet-connected devices and support future technological advancements.


2. Evaluating IPv6 Adoption

Before deciding to sell IPv4 addresses, it’s crucial to assess the current state of IPv6 adoption. While IPv6 deployment is steadily increasing, it is still not universally implemented. Consider factors such as your target market, customer base, and network requirements. If your organization primarily operates in regions or industries where IPv6 adoption is minimal, there may still be a demand for IPv4 addresses.


3. Assessing Market Demand

Evaluate the market demand for IPv4 addresses in your region and industry. Determine if there is a sufficient buyer pool and whether the demand outweighs the supply. Research the pricing trends and recent transactions to gain insights into the market dynamics. Engaging with reputable IPv4 brokers or marketplaces can provide a clearer picture of the demand for IPv4 addresses.


4. Addressing Future Network Growth

Consider your organization’s future network growth plans. If you anticipate significant expansion or the need for a large number of IP addresses, it may be prudent to retain your IPv4 addresses. However, if your growth strategy aligns with IPv6 adoption, selling your IPv4 addresses could generate immediate financial returns and support your transition to the new protocol.


5. Weighing Financial Returns

Evaluate the financial returns you can expect from selling your IPv4 addresses. Assess the market value of your addresses based on factors such as scarcity, regional demand, and address block quality. Engage with reputable brokers to obtain accurate valuations and explore potential deals. Consider your organization’s financial goals and whether the returns from selling IPv4 addresses align with your strategic objectives.


6. Managing Address Utilization

Assess your current address utilization. If you have a surplus of IPv4 addresses that remain unused or underutilized, selling them can unlock their value and provide resources for other business initiatives. However, if your address utilization is optimal or if there are specific legacy applications that rely solely on IPv4, retaining your addresses may be necessary.


7. Mitigating Risks and Legal Considerations

Consider the potential risks and legal considerations associated with selling IPv4 addresses. Ensure compliance with the transfer policies and regulations set forth by the Regional Internet Registries (RIRs) or relevant authorities. Work with reputable brokers who can navigate the legal aspects and mitigate any potential risks.



Deciding whether to sell IPv4 addresses requires careful consideration of multiple factors. Evaluating the current state of IPv6 adoption, assessing market demand, addressing future network growth, weighing financial returns, managing address utilization, and mitigating risks are all crucial steps in making an informed decision. While the transition to IPv6 is inevitable, the timing and market dynamics play a significant role in determining whether selling IPv4 addresses at this moment is the right choice for your organization. Assess your unique circumstances, consult with experts, and align your decision with your strategic goals to make the most informed choice regarding your IPv4 addresses.
