IPv4 Markets

The AFRINIC Saga - a Firestorm in Haven

The ongoing saga at the African Network Information Centre (AFRINIC), which distributes Internet addresses in Africa, is a threat to the stability of the global Internet and emblematic of Africa's governance challenges. When you want to visit a Website, you generally use a domain name (e.g., hell.com). The domain name is then translated to an address, called a unique Internet Protocol (IP) address, which every device connected to the Internet has while it is connected. more

The 2022 IPv4 Market in North America

In 2021, the story was price. In 2022, the story was price and large block supply. Spurred by unprecedented unit pricing, the IPv4 market in North America experienced its second-best year ever in market history. Nearly double the number of IPv4 addresses were traded in 2022 compared to 2021, predominantly due to the increased flow of large block supply from twelve sellers, five of whom were first-time market participants. more

The IPv4 Price Inversion

A curious price inversion has occurred in IPv4 markets. The long-term trend that discounted large blocks has reversed. The graph identifies /15 and /16 (large) block pricing per IP address throughout the period in the form of dark spots. It is evident that, for most of the timeframe here (2014 to the first half of 2021), large blocks sold at a significant discount. One might guess that the administrative chores related to large-network needs were most efficiently and cheaply satisfied with large blocks. more

Some Random Notes from IETF 115

The IETF held its 115th meeting in London in November 2022. This was another in the set of hybrid meetings with specific support for online attendees in addition to the normal face-to-face meetings for the week. In no particular order, here are a few of my impressions from the IETF meeting. more

The Short History of the Internet: From ARPANET to the Metaverse

Last Saturday marked the 53rd anniversary of the Internet. While the vast majority of its five billion users have been online for less than a decade, the Internet was taken into use on October 29th, 1969, when two computers connected to the ARPANET exchanged a message. Although the Internet has been around for a while, it remained below most people's radar until the late 1990s when the dot com boom started. more

Saint Martin Launches Smart-IX Internet Exchange Under CaribIX Project

The recent launch of a new internet exchange point in Saint Martin has propelled the territory towards a better, faster and more resilient Internet. The French Caribbean territory's new IXP, called Smart-IX, was launched in October under the auspices of a recently launched CaribIX project, which is coordinated by the Caribbean Telecommunications Union (CTU), supported by the Caribbean Network Operators Group (CaribNOG), funded by the INTERREG Caraïbes programme... more

Hijacked IP Addresses

From time to time, a party can get out of control. Raucous celebration can become careless, even destructive. Combine a critical number of young people, a certain amount of beer and lots of music and damage often happens. Partygoers leave a mess behind them. The same thing happens to some IP addresses. Malicious actors use IP addresses properly registered to someone else. more

IP Address Location Data

The last few years have shown us how the Internet shrinks distances between distributed teams, organizations and families. This poses a challenge for some organizations. Many business relationships and contractual agreements involving the Internet have geographical implications and restrictions. This matters to anyone operating a network. It is most important for networks that get new address space. more

The Hidden Value of IPv4 Addresses

All devices that connect to the internet need unique addresses. The number of IP addresses is limited, creating a demand for addresses worldwide, particularly from the cloud computing industry. This demand has raised the value of IPv4 to levels that the internet's original developers didn't predict, in part because the internet was considered an experiment at the time. Of course, use - and so demand -- has exceeded anyone's realistic expectations. more

IP Address Blocking

A network can fence its own IP addresses or block specific external ones from access. Administrators frequently block access to their own IP addresses to bar unwanted access to content. Individual IPs or blocks of IPs may also be blocked due to unwanted or malicious behavior. IP address blocking prevents a specific IP address or group of IP addresses from connecting with a server, computer, or application. more

CIDR in Networking: Improved IP Routing Efficiency

CIDR (Classless Inter-Domain Routing) is a routing system in which network engineers can distribute IP addresses based on the size of their specific network. This is more efficient than the previous system, which assigned IP addresses depending on whether the size of a network fits into one of only three sizes: Class A, Class B, and Class C. more

Implications of DoD IPv6 Mandate on IPv4 Market

Recent Department of Defense IPv4 activity and announcements about IPv6 indicate a shift in their perspective and suggest potential impacts on the IPv4 address market. The shift could include the release of up to 175 million IPv4 addresses in the coming years, creating a risk of a glut in the market. For perspective, the market has transferred 380 million addresses over eleven years. more

Sanctions & The Regulation of IP Transfers

The early stages of internet development operated in a culture of independence from outside influence. In fact, as though to commemorate the spirit of the times, in 1996, John Perry Barlow wrote "A Declaration of the Independence of Cyberspace." In it, he told governments they "have no sovereignty where we gather." He went on to state, "Ours is a world that is both everywhere and nowhere, but it is not where bodies live." more

Minding Your IP Address Reputation

Network operators rely on guidance from IP address experts because not all IP addresses used on the Internet are the same. The "reputation" of email senders is especially important because some are malicious users of the system. But identifying "senders" based on their email addresses or the individual IP address of a user presents issues that are unnecessarily complex. more

The IPv4 Market in 2021

Price was the story of the 2021 IPv4 market. Large and small organizations alike continue to invest in their IPv4 infrastructure causing demand for IPv4 address space to intensify. Meanwhile, supply remains constrained. These market factors drove prices up at a historic rate in 2021. more
