The Time Square Ball bringing in 2008 had more than 9,500 LED bulbs displaying 16 million colours while consuming power equivalent to about ten toasters. This compares to 600 incandescent and halogen bulbs adorning last year's Ball. Easy to forget that most mobile devices used by Time Square revelers were behind IPv4 NAT's and that always on applications such as Instant Messaging, Push e-mail, VoIP or location based services tend to be electricity guzzlers. It so happens that applications that we want always to be reachable have to keep sending periodic keepalive messages to keep the NAT state active... more
What would duopoly providers of internet access really like to have? They'd really like to be paid for providing non-commodity services. They'd really like to be rewarded for running the network, top to bottom. "But that's not possible," you say. No provider can tell one packet from another. Providers can only block the ports used by applications they don't like, and that's a clumsy, unwinnable arms race. The applications can always switch to common and useful ports, and no provider wants to alienate its subscriber base. But what if providers could inspect the contents of packets, without using too much computational power, and discriminate among applications? "Naah," you say. "They can't possibly do that."... more
Building IoT ventures from scratch by prototyping hardware devices and their backend systems as well as working for a large company that tries to sell IoT devices itself, we learned a lot about the pitfalls and problems concerning security in the IoT. Nearly every connected device out there proved to be vulnerable to attacks. Researchers showed that it's possible to remotely take control over autonomous vehicles, implanted medical devices were manipulated, voting machines compromised and of course all sorts of other "smart" devices... more
Cities are among the largest regional authorities and natural human communities we know. Of course there are countries like China, India or the USA which count some hundred million or even a billion inhabitants. But there are also countries with far less than 100,000 inhabitants, like Tuvalu, Andorra or Barbados. If city communities are ranked by the number of inhabitants as independent entities among country communities, cities like Tokyo, New York, Shanghai or London head the ranking because they have more citizens than many countries. London for instance has more inhabitants than the Netherlands, and Tokyo outpaces Canada in that respect. Interestingly, there are only around 400 cities worldwide with more than 1 million inhabitants... The following post will give an overview of how cities are being identified on the Internet via Top-Level Domains and the opportunities that lay ahead. more
Ah yes, 'Security by obscurity': "Many people believe that 'security through obscurity' is flawed because... secrets are hard to keep." I'm glad the guys guarding the A Root Servers are up on the latest security trends. Of course, you could hide the A Root Servers at the heart of the Minotaur's maze, but they're still going to be "right over there" in cyberspace, at 198.41.0.29 more
This growth is clearly unsustainable within the IPv4 address space. Not every country can have these utilization levels. The hunger for new addresses is greatest in China (currently at 1 IPv4 address per 4 inhabitants) and India (1 address per 53 inhabitants). To put these at the modest level of 1 address per inhabitant requires more than 2.2 billion addresses, where there are currently only 290 million left... Given these numbers and the overall strong growth, any hopes of being able to reuse space that is allocated but not used (i.e. pre-CIDR) are futile. This demand dwarfs the entire US allocation. more
The U.S. government has announced today that it will indefinitely retain oversight of the Internet's root servers, ignoring pervious calls by some countries to turn the function over to an international body. more
On October 16, 2003, VeriSign announced the sale of its Network Solutions (NSI) business unit three years after its purchase from SAIC. This is a report on the historical snapshot of Network Solutions and a collection of commentaries made in response to this event...Network Solutions, Inc. was founded by Emmit J. McHenry as a joint venture with the National Science Foundation and AT&T... more
In the beginning there was silence; then, silence begat communication, and communication begat more communication and, ultimately, group communication formed and begat a primordial "network" of communication that gradually and inevitably increased in effectiveness and complexity: there were only signal fires at first but, then, there were cave drawings, carrier pigeons, shouting from hill-tops, smoke from fire, lines of cannon fire, the telegraph, Alexander Graham Bell, and, finally, the network of networks known as the Internet. But, is that it? Is there not something more impressive in its impact upon communication than the Internet? What more might one desire than the dynamic wonders of the Internet, you ask? Well, what about ENUM? "E-What!?" more
Until the pandemic hit, I rarely thought about upload bandwidth. I mostly used upload bandwidth to send files to people, and I rarely cared if they received the files immediately -- I was happy as long as files got sent. But the pandemic changed everything for millions of people. All of a sudden, homes were unable to function well due to problems with uploading. more
For about the last two years, I was a member of ICANN's At Large Advisory Commitee (ALAC), the group charged with representing the interests of ordinary Internet users within ICANN. In case anyone is wondering, here's why I'm not on the ALAC any more. ICANN has a very narrow mission. They maintain the root zone, the list of top-level domain names in the Internet's domain name system. They coordinate numeric IP addresses, with the real work delegated to five Regional Internet Registries. And they keep track of some simple and uncontroversial technical parameters for Internet routing applications... more
Nominet has published a very detailed and comprehensive position paper on "front running". Although the paper is a mere 5 pages long it covers all the areas that the topic encompasses very well and is well worth a read. The topic of "front running" has received some publicity in the last few months. If you're not familiar with the concept Nominet's definition is helpful... more
In a press release issued Wednesday, March 03, 2004, Go Daddy Software, Inc., defended ICANN's right to regulate VeriSign's registry services and called for a formal review of the company's position as an "exclusive registry." This announcement from Go Daddy, which comes one week after VeriSign filed a lawsuit against ICANN, pledges $100,000 to ICANN for its defense of the VeriSign lawsuit. Go Daddy, which ranks among the top 3 largest domain name registrars in the world and one of VeriSign's largest customers, has also sent a letter to both the U.S. Department of Commerce (DOC) and the Internet Corporation for Assigned Names and Numbers (ICANN) strongly urging both groups to undertake a formal review of VeriSign's registry position.
In this special interview, CircleID has caught up with Bob Parsons, President and Founder of Go Daddy, where he provides in-depth discussions of Internet Innovation, ICANN, VeriSign's Global Registry Services, Top-Level Domains and the current legal battles. more
The new organization called Coalition for ICANN Transparency (CFIT) has filed a lawsuit against ICANN and VeriSign in order to stop implementation of the proposed .com registry agreement. According to its description, "CFIT is a not-for-profit Delaware corporation based in Washington, D.C. CFIT’s supporters include individuals, organizations, institutions and companies who are committed to the core principles on which ICANN, the internet governing body is founded." more
The following is an analysis based on the hypothesis that trademark holders are not, in general, registering their trademarks as domain names across the existing top-level domain namespace. To determine if the hypothesis is true, we examine domain names registered in the popular generic top-level domains ("gTLDs" such as .com, .net and .info), also using other publicly available information such as the USPTO database of trademarks, the English dictionary, DNS entries, UDRP records and whois records. more
