Spam Arrest’s Sender Agreement Fails Because Email Marketer’s Employees Lacked Authority

People hate receiving spam, but most people stopped obsessing about spam a decade ago or more. In the interim, anti-spam filters have improved dramatically. Still, some anti-spammers hate spam so passionately -- or, perhaps, hope to put a little coin in their pockets -- that we still see a steady stream of lawsuits against email marketers. For the most part, those lawsuits don't win; in the past half-decade, repeat anti-spam plaintiffs have rarely won in court. more

Wow. That’s a Lot of Reserved Names

ICANN recently updated the list of reserved second level domain names. Those are names that you won't be able to register in any of the 1500 or so new domains they're planning to add. There's rather a lot of them, currently 629. The names are in three groups, the ICRC (the Red Cross), the IOC (the Olympic games) and everyone else. Several years ago the Red Cross and later the Olympics came to ICANN and insisted that they make a special list of forbidden names, separate from the various trademark registries. 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

Neustar Analysis Shows ICANN Study Overstates Risk of Harmful Domain-Name Collision

As we blogged about recently, Neustar is committed to ensuring that the domain name system is secure and stable and has been operating top-level domains (TLDs) for over a decade. Tuesday, Neustar submitted comments to the Internet Corporation for Assigned Names and Numbers (ICANN) in response to ICANN's proposal to delay the launch of hundreds of new generic top-level domains (gTLDs). ICANN's decision to delay the launch is based on a study it commissioned that measured the potential frequency of domain-name collision. more

Who Are the True Multi-Stakeholders in ICANN?

During ICANN Durban, I attended the Country Code Names Supporting Organisation (ccNSO) 10 year anniversary celebrations. ICANN Chairman, Dr Steve Crocker, was on hand to congratulate the ccNSO on their 10 years and revered them as the "true multi-stakeholders in ICANN". Post Durban, I was reviewing notes and I came across a similar statement made during a ccNSO session that country code Top-Level Domains (ccTLDs) "represent the best functioning multi-stakeholder model" in the ICANN ecosystem. Is this entirely accurate? more

Telecoms a Double-Edged Sword for the Industry

The telecommunications business is a double-edged sword. On the one hand it is an enormous growth industry because of its function as a key facilitator in the transformation of societies and economies towards a future that is driven more and more by ICT developments. Over the last decade companies such as Google, Apple, Samsung, Amazon and Facebook have made it to the list of the most successful businesses... On the other hand many of the traditional telco businesses operating in this market are recording declining results. more

Mass Surveillance: A Turning Point in Internet History

So far, the debate on mass surveillance has dwelt on the immense resources made available to the agencies (NSA in the US, GCHQ in the UK), on the technological advantage that enables them to access any data and bypass encryption, and on the lack of proper oversight in those two countries. But in order to make their voices heard by their elected representatives, Internet users around the world need to have an even more complete view of the emerging reality. more

How Not to Stop Spammers

Spam Arrest is a company that sells an anti-spam service. They attempted to sue some spammers and, as has been widely reported, lost badly. This case emphasizes three points that litigious antispammers seem not to grasp: Under CAN SPAM, a lot of spam is legal; Judges hate plaintiffs who try to be too clever, and hate sloppy preparation even more; Never, ever, file a spam suit in Seattle. more

The Discrepancy in Confusion and Similarity Decisions of New gTLDs

After more than half of the new gTLD String Confusion Objection determinations that have been published we have updated our popular chart which compares the Visual Similarity (determined by the SWORD tool) with the results of the String Confusion Objections. We found that there is a huge discrepancy in what has been expected in the ICANN community and what the "Experts" have be decided. more

On the Time Value of Security Features in DNS

There are some real problems in DNS, related to the general absence of Source Address Validation (SAV) on many networks connected to the Internet. The core of the Internet is aware of destinations but blind to sources. If an attacker on ISP A wants to forge the source IP address of someone at University B when transmitting a packet toward Company C, that packet is likely be delivered complete and intact, including its forged IP source address. Many otherwise sensible people spend a lot of time and airline miles trying to improve this situation... The problems created for the Domain Name System (DNS) by the general lack of SAV are simply hellish. more

Travelogue Broadband Experiences

Throughout this year I have once again travelled extensively through USA, Europe, Asia and Latin America. Naturally, being in this industry I watch closely the various developments in broadband, mobile and WiFi. When you are travelling obtaining access is never far from one's mind. This also provides good opportunities to compare what is available, where, what the quality is, and so on. Looking back over many years there is no doubt that, no matter where you travel, there has been incredible progress. more

Diagnosing Load Test Errors - Where to Start for Holiday Success

Picture this: you just completed hours of internal Web services preparations with your system administrative team prior to the holidays. You discovered possible points of failure and made appropriate modifications with the expectation of a perfect load test. You take a few minutes to relax, refill the coffee mug sitting in front of you, and connect to the conference bridge where real-time discussion about the load test will occur. Things go well for the first 20 minutes of the test... Then it happens: one of the simulated users logs an error stating that it has timed out. more

You Just Signed a Registry Contract With ICANN. What Are Your Plans?

Back on February 4, 2013, I wrote a CircleID post entitled 'How the registrar Cash Flow Model Could Collapse with New ICANN gTLDs.' My key point back then was this: new gTLD applicants need to be mindful of how the cash flow policies of their registry (and of their back-end service provider) could impact whether their TLD is actively promoted by ICANN registrars... registries have historically assumed near-zero risk. This is going to change. more

Plumbing Neutrality

I've been having arguments about Network Neutrality with a lawyer. My position is that you can't adequately regulate ISPs to be neutral, because there's no agreement what "neutral" means in practice. He points out that the courts aren't interested in technical details like what packets are dropped, it's that all traffic has to be treated the same, and ISPs should just figure out how to do that. So I contemplated a city with Plumbing Neutrality with the simple rule that all people must be treated the same... more

Reflections on EUI’s New Community Priority Evaluation Guidelines for New gTLDs

The new Community Priority Evaluation (CPE) guidelines prepared by the Economist Intelligence Unit (EIU), and published by ICANN are now past their feedback period. We, at Radix, believe that ICANN has received feedback from approximately 10 stakeholders, and I for one, am looking forward to those being published. In light of the fact that none of the comments that ICANN received have been made public yet, I decided to blog about my multiple concerns with the new guidelines. Sparing a thought for the not-so-involved reader, I have limited my rant to some of the more important issues. more
