IPv4 Markets / Most Commented

Explaining China’s IPv9

Recently, the news that China is adopting IPv9 is making rounds on the Internet. While some of them write off as an April Fool's joke (in July?) like RFC 1606, other wonders if there are more than meets its eyes. But most of them wonders what is this IPv9 and how does it actually works. And some of the English translated article are so badly done that it is impossible to get any useful technical information except that 'It is developed and supported by Chinese government!' more

DNS WHOIS: Barking Up the Wrong Tree

As the Internet has grown and matured, it has become obvious to everyone involved that the DNS Whois system, as it currently exists, is not a sustainable way to share contact information for resolving network problems. ICANN, in an attempt to save DNS Whois, has plunged head long into the process of developing new policies aimed at fixing it. While I respect all of the hard work that has gone into this process, the results thus far have only made it clearer that this system faces intractable problems. more

Search Engine Optimization: Static IP vs. Dynamic IP Addresses

This is a hotly debated topic. Some Search Engine Optimizers (SEOs) claim that sites with a static IP address rank higher while other SEOs claim that shared hosting is just fine... that it would be stupid for search engines to penalize shared hosting since we are running out of IP addresses and so many sites are currently using name based hosting. ...I decided to run it through our statistical analysis engine to get the facts. Here is the methodology I used to answer this question. more

When Did We Give Away the Internet?

I've been following the recent news on the World Summit on the Information Society, and it's getting really bizarre. The Wired article is one example of out of the out-of-this-world coverage on the World Summit; I heard a similar spin yesterday on a radio show that often shares material with the BBC. What king or dictator or bureaucrat has signed the document giving power over the Internet to one organization or another? Did I miss the ceremony? One laughable aspect of news reportage is that the founders and leaders of ICANN always avowed, with the utmost unction, that they were not trying to make policy decisions and were simply tinkering with technical functions on the Internet.  more

Why Do We Care About Names and Numbers?

An article based on the most recent study for the European Commission on the Policy Implications of Convergence in the Field of Naming, Numbering and Addressing written by Joe McNamee and Tiina Satuli of Political Intelligence.

"With relation to the Internet and also IP addresses, the "scarcity" is more complicated: there are not only intellectual property issues with regards to domain names, but there is also an issue of managing the integrity of the system. For any naming or numbering system to work, it is essential that the names and addresses used cannot be confused with any other -- in other words, no one system can have two end-points with the same fully qualified number or name..." more

Moving Target: Spammer Using Over 1000 Home Computers as DNS

Some individual appears to have hijacked more than a 1,000 home computers starting in late June or early July and has been installing a new Trojan Horse program on them. The Trojan allows this person to run a number of small websites on the hijacked home computers. These websites consists of only a few web pages and apparently produce income by directing sign-ups to for-pay porn websites through affiliate programs. Spam emails messages get visitors to come to the small websites.

To make it more difficult for these websites to be shut down, a single home computer is used for only 10 minutes to host a site. After 10 minutes, the IP address of the website is changed to a different home computer... more

ICANN’s New gTLD Round Draws 16 African Applications, 10 Controlled by a Chinese Business Network

A Seychelles company controlled by Lu Heng accounts for 10 of Africa's 16 new gTLD applications, linking ICANN's domain expansion to commercial interests and an ongoing dispute over AFRINIC's governance and IPv4 resources. more

IPv4 Has Two Clocks: Why Acquisition and Deployment Don’t Move at the Same Speed

IPv4's fixed supply masks a crucial mismatch: addresses can be acquired quickly but deployed only gradually. After 2025's price declines, returns increasingly depend on lease rates, absorption speed and the operator's ability to monetise inventory. more

AFRINIC’s Constitution Is Africa’s Next Internet Stress Test

AFRINIC's proposed Constitution offers Africa's troubled internet registry a chance to turn years of litigation, disputed elections and institutional paralysis into durable governance, provided reforms constrain external capture, internal concentration and administrative overreach alike. more
