ARIN Addressing the Challenge: The Growing Demand for IP Addresses

December 1, 2023

Striving to Meet the Needs of a Growing Digital Landscape

In today’s interconnected world, where digital technologies drive our everyday lives and power businesses of all sizes, the demand for IP addresses continues to rise rapidly. However, the supply of available IP addresses is limited, posing challenges for organizations seeking to secure the necessary resources to operate effectively in the online realm. One organization at the forefront of managing this demand is the American Registry for Internet Numbers (ARIN).

The Growing Waiting List at ARIN

ARIN serves as the Regional Internet Registry (RIR) for North America, responsible for allocating and assigning IP addresses within its region. Yet, despite their efforts, the sheer magnitude of requests compared to the available pool of IP addresses presents a significant challenge. On average, ARIN receives approximately 150 requests each quarter, but they can only fulfill 30-50 of those requests. This discrepancy highlights the growing gap between demand and supply in the IP address space.

To put this into perspective, there are currently over 700 companies on the waiting list at ARIN, eagerly awaiting their share of IP addresses1. As these businesses strive to establish their online presence, expand their networks, or accommodate the increasing number of connected devices, the need for IP addresses becomes paramount.

The Internet of Things (IoT) Revolution

Several factors contribute to this surge in demand. First and foremost, the exponential growth of the internet and the proliferation of internet-enabled devices have fueled the need for more IP addresses. From smartphones and tablets to Internet of Things (IoT) devices and cloud infrastructure, each connected device requires its unique address to communicate effectively over the internet.

Additionally, the emergence of new technologies, such as 5G networks and edge computing, further intensifies the demand for IP addresses. These advancements promise faster speeds, lower latency, and enhanced connectivity, but they also require a substantial allocation of IP addresses to support their infrastructure.

Depletion of IPv4 Addresses and the Transition to IPv6

The scarcity of available IP addresses stems from the depletion of IPv4 addresses, the traditional addressing system widely used today. The remaining pool of IPv4 addresses is rapidly depleting, necessitating the adoption of IPv6, the next-generation internet protocol. IPv6 offers a significantly larger address space, with the potential to accommodate the growing number of devices and users on the internet. However, the transition to IPv6 poses its own set of challenges, including compatibility issues and the need for infrastructure upgrades.

To tackle this issue, ARIN actively encourages organizations to adopt IPv6 and has implemented various initiatives to promote its adoption. These efforts aim to alleviate the strain on the limited IPv4 resources, allowing organizations to continue expanding their networks without exhausting the remaining pool of IPv4 addresses.

ARIN’s Challenge: Fulfilling Requests Amidst Limited Supply

In conclusion, the demand for IP addresses continues to outpace the supply, presenting a pressing challenge for organizations seeking to establish and expand their digital footprint. With approximately 150 requests each quarter but only 30-50 being fulfilled, the waiting list at ARIN continues to grow, currently comprising over 700 companies. The transition to IPv6 serves as a long-term solution to address the scarcity of IP addresses, enabling the internet to accommodate the increasing number of devices and services. As we navigate this evolving digital landscape, it is imperative for organizations to embrace IPv6 and collaborate with RIRs like ARIN to secure the necessary resources and sustain the growth of our interconnected world.
