Geeks All Trust Each Other But Not in China

Brian Krebs has a post up the other day on his blog indicating that the amount of spam ending in .cn has declined dramatically due to steps taken by the Chinese government making it more difficult to get a domain ending in .cn... A cursory glance seems to confirm that the amount of spam from .cn as opposed to .ru has switched places. Indeed, if the CNNIC requires people to start writing in application forms, with a business license and identity card, that is seriously going to slow down the rate at which spammers can sign up and register new domains. more

Why Fiber?

As much as I've written about broadband and broadband technology, it struck me that I have never written a concise response to the question, "Why Fiber?". Somebody asked me the question recently, and I immediately knew I had never answered the question. If you're going to build broadband and have a choice of technologies, why is fiber the best choice? more

Sprint Fights for Mobile Market Relevance: First Quarter Earnings Positive

Sprint's vision along with determined action says everything. They are fighting for mobile market relevance, thumbing their noses at detractors, moving beyond being relegated to a distant 3rd ranked carrier in a fast growing market. It's acquisition of the iPhone and agreement to spend $15.5 Billion over four years for the privilege has investors squawking bankruptcy sooner rather than later. First quarter earnings reveal that Dan Hesse's decision to purchase iPhones back in October 2011 is paying off in solid contracts. more

DNS Amplification Attacks: Out of Sight, Out of Mind? (Part 3)

Previous posts (Part 1 and Part 2) offer background on DNS amplification attacks being observed around the world. These attacks continue to evolve. Early attacks focused on authoritative servers using "ANY" queries for domains that were well known to offer good amplification. Response Rate Limiting (RRL) was developed to respond to these early attacks. RRL, as the name suggests, is deployed on authoritative servers to rate limit responses to target names. more

What the Internet Is, and Should Continue to Be

Occasionally, people ask my perspective on the Internet, since I often object to confusing it with things like the telephone or Cable TV. Recently I composed a response that captures my perspective, as one of the participants in its genesis, and as an advocate for sustaining its fundamental initial design principles. I hope these words clarify what I believe many of those who continue to create the Internet continue to do, even though most of them are not aware of it. I also hope many will see their interest in keeping the core principles of the Internet alive. 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

ICANN Policymaking Should Be Even More Transparent

Transparency and accountability are embedded in ICANN's core values. Indeed, ICANN's Bylaws mandate that "ICANN and its constituent bodies shall operate to the maximum extent feasible in an open and transparent manner ...". Public Interest Registry believes that a dedication to transparency is fundamental to the strength and continued effectiveness of ICANN's multistakeholder model. more

CE Router Certification Opens Up the Last Mile to IPv6 Fixed-Line

With reference to IPv6, probably most end users do not have any sense of it. The mainstream condition in the industry is that network carriers and content/service providers stick to their own arguments. Carriers consider lack of IPv6 content and service as the reason demand for IPv6 from the users is very low. The content and service providers believe that users cannot have access to content and service through IPv6 and thus carriers should provide the service in the background. more

Switching on the Light: Expression of Interest for New TLDs

They say late converts are the most passionate believers. Until now I haven't supported the Expression of Interest (EOI) for new TLDs, the proposed mechanism to measure the number and type of likely applications. Not because it won't work (I think it'll work fine) but because I didn't think it was necessary. I've changed my mind. Here's why. more

Hot Architectural Issues for the Internet

The Internet Architecture Board's (IAB) chair, Olaf Kolkman, asked the members of the IAB to provide a statement paper each on what they believe the current most pressing issues in terms of Internet architecture are... I have thought about this for the past few days, and realised that it's hard to come up with overarching issues and even harder to come up with issues, where the IAB actually could make a difference. But I came with up with two issues. more

If Slate Comes in Standard Sizes, Why Not Broadband?

Last week I was at the National Slate Museum in Wales watching slate being split apart. On the wall were sample pieces of all the standard sizes. These have cute names like "princess". For each size, there were three standard qualities: the thinnest are the highest quality (at 5mm in thickness), and the thickest have the lowest quality (those of 13mm or more). Obviously, a lighter slate costs less to transport and lets you roof a wider span and with less supporting wood, hence is worth more. more

Satellites and Cellular Backhaul

Elon Musk recently announced that he was going to be providing cellular backhaul from the Starlink constellation of satellites. This makes a lot of sense from a financial perspective in that it avoids the costly wired fiber networks needed to reach rural cell sites. This is clearly a shot across the bow for companies that currently bring fiber connectivity to rural cell sites. more

Who Has Helped the Internet? May 31 Deadline for Nominations for 2013 Jonathan Postel Service Award

Do you know of a person or organization who has made a great contribution to the Internet community? If so, have you considered nominating that person or organization for the 2013 Jonathan B. Postel Service Award? The nomination deadline of May 31 is fast approaching! more

Nominet/SOCA Cyber Crime Proposal: Allow Cross Border Reactions

Reading the policy proposal of Nominet, I get the feeling that something is overseen here. Putting all the jurisdictional hassle aside for a moment, cyber crime is international, cross-border. So what happens if a UK domain is used for criminal activity outside the UK only? more
