The Issue Is the Digital Economy, Not Broadband

After some five years of public debate on the national broadband network it is heartening to see that more and more people are getting the message that the network means more than just fast internet access. Increasingly key decision-makers in business and government are reaching an understanding of the transformation that is underway in the economy. more

Spectrum Crisis: Wireless Auctions Preferred Method

Talk, conjecture and analysis have predicted a wireless spectrum crisis for years. The official word seems to project a culmination of dropped calls, slow loading of data, downright network access denials as impending by 2015. If so, then we should look at the current argument about how that additional spectrum can be disseminated to wireless carriers in a fair and balanced fashion. more

IPv6: Childhood’s End?

A few weeks ago, when I was lurking around IPv6, I found that my own www.ipv6.tk was my first ever IPv6 domain. A "whois" on the domain says that it was registered in 2005, but something told me that I actually started this earlier. ?I therefore logged in at www.nic.tk and could see that my first feeling was correct; the first invoice for ipv6.tk was actually paid in the year of 2002. Here are some of the key things that I have experienced and learned over my first ten years. more

US Telecoms Market Further Deteriorating

Some worrying signs are emerging in the USA. During the last decade I have questioned the economic viability of two parallel telecoms infrastructures. When these two network rollouts commenced no issue existed in relation to conflicting interests -- one delivered telephone services, the other broadcasting services. But this all began to change when it became possible to use the HFC network more

Measuring Root Server Performance

Root name servers are a core service of the Internet. As such they receive a huge amount of queries and need to answer reliably with acceptable delay. The RIPE NCC is responsible for operating one of the 13 DNS root name servers K-root which responds to 10,000 - 15,000 queries per second. Most root servers are operated as a network of distributed "instances" using anycast. more

Mobile Broadband Boom: The Killer App for FttH

It still amazes us that respected industry commentators join liberal politicians in questioning the need for FttH in the wake of the enormous success of mobile broadband. They refer to this phenomenon as proof that people are bypassing their fixed broadband and are now using the smartphones and tablets to obtain most of their broadband access. However, after several years of mobile boom the majority of households are still using the fixed-line networks for calls... more

Most Abusive Domain Registrations are Preventable

As the WHOIS debate rages and the Top-Level Domain (TLD) space prepares to scale up the problem of rogue domain registration persists. These are set to be topics of discussion in Costa Rica. While the ICANN contract requires verification, in practice this has been dismissed as impossible. However, in reviewing nearly one million spammed domain registrations from 2011 KnujOn has found upwards of 90% of the purely abusive registrations could have been blocked. more

Closing the Gaps: The Quest for a Secure Internet

Over the last year the world has been virtually buried under news items describing hacks, insecure websites, servers and scada systems, etc. Each and every time people seem to be amazed and exclaim "How is this possible?" Politicians ask questions, there is a short lived uproar and soon after the world continues its business as usual. Till the next incident. In this blog post I take a step back and try to look at the cyber security issue from this angle... more

End of the World/Internet on 31-March-2012?

Well... Maybe not the world, but the Internet it seems. According to a Pastebin letter, Anonymous announced they will black-out Internet on 31st of March. They even explained how to do it by attacking the DNS Root Servers on Internet using a reflected amplification attack. If this is successful, the root DNS servers will become unresponsive and cannot handle any other requests... more

Anonymous Plans to Go After DNS Root Servers. What Will Be the US’s Response?

The other day on pastebin, snippets of an email conversation were posted with members of the hacking group Anonymous discussing plans to conduct DOS attacks against the Internet's root name servers... Going after the Internet's root servers is a very bold move by Anonymous. Whereas before they were "merely" breaking into companies that they believed were acting contra to the hacker ethic, going after the Internet infrastructure is another thing altogether. Why? more

Google’s Free Public DNS Load Tops VeriSign, Raising Dot-Com Contract Tender Question

Google revealed on its official blog today that it is handling an average of more than 70 billion requests per day on its free Public DNS service. According to VeriSign's latest public statistics, it is handling only an average of 59 billion DNS requests per day, less than that handled by Google. more

Debilitating Cyber Attack: Not If, But When?

We all know how easy it can be to ignore or underestimate the possibly, or even likelihood, of a terrorist attack; just remember what happened on 9-11. That seems to be just what the U.S. is doing when it comes to a possible Cyber-Attack, no not in other countries, but right here at home where targets like private sector companies, who provide vital economic and emergency services to our population using broadband infrastructure, and are woefully under-secured for such attacks. more

MegaBust’s MegaQuestions Cloud the Net’s Future

Mid-January 2012 marked a major inflection point for digital copyright policy in the United States... Yet no one involved with Congressional interaction on either side of the issue believes it has been sidetracked for long, and "Hollywood" and "Silicon Valley" are both plotting their next moves in this high-stakes game to further define the responsibilities and potential liabilities... The resolution of this dispute will determine the ability of Internet services to move to "the cloud"... more

How Frequently Do Botnets Reuse IP Addresses?

I wonder how much botnets reuse IP addresses. Do they infect a system and spam, get blocked, discard the IP and move onto the next (new) one? This means that they have a nearly unlimited supply of IP addresses. Or do they infect a system and spam, get blocked, and then let it go dormant only to awaken it some time later? I decided to take a look. more

Green IT Revolutionizing UK Cyber-Infrastructure via Networks, Cloud, Outsourcing, Finan. Incentives

As readers of my blogs may know I have long argued that advances in research and education through cyber-infrastructure (or eInfrastructure) can be largely justified, if not entirely paid for through the energy savings of using clouds, networks or outsourcing. But a big impediment in adopting cyber-infrastructure in most jurisdictions is the lack of financial incentives. The energy savings of cyber-infrastructure are usually earned by the facilities or estates department or rarely based on to researchers and educators. more
