Is the glass half full or half empty? The human reflex of selective deafness to information or arguments countering one’s established believes lives on. The ISOC organized lunchtime IPv6 panel at IETF 74 in San Francisco illustrates the point... more
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
The 7th meeting of the UN Broadband Commission in Mexico City was again a good combination of announcements about new plans, results of previously undertaken activities, and views on the future of broadband. Very noticeable was the enthusiasm and acknowledgement of the impact of ICT, and of broadband in particular. In September 2012 the Commission launched its working group on gender equality. Research undertaken by the various members of the workgroup provided somewhat similar results. more
The blog on the need for a new internet received quite a bit of (international) attention, and with the assistance of colleague John Day, we would like to elaborate a bit further on this. I mentioned RINA as a good example that can be used to have a look at how such a new internet should look like. Interestingly the basics are not all that new. Already in the 1970s, but certainly two decades later, there were plenty of telecoms and computer engineers who started to understand that the future telecommunications work would have more to do with computing than with telecoms. more
Josh Baer, former VP of Datran Media and current CEO of OtherInBox has been floating an idea at the DMA's Email Experience Council and a few other places, and recently got some traction in Ken Magill's Magill Report. What Josh is proposing is to create the technical means by which a Sender can decide when email 'expires' and is automatically removed from a recipient's inbox, either by deletion, or perhaps archiving (in the case of Gmail). This would supposedly help the end-user, by removing marketing offers that are no longer available. Why this idea shouldn't happen... more
There has long been pressure from governments to provide back doors in encryption systems. Of course, if the endpoints are insecure it doesn't matter much if the transmission is encrypted; indeed, a few years ago, I and some colleagues even suggested lawful hacking as an alternative. Crucially, we said that this should be done by taking advantage of existing security holes rather than be creating new ones. more
On April 20, 2017, an 8-person delegation led by Göran Marby, President & CEO of ICANN, visited China Academy of Information and Communication Technology (CAICT). Madam Liu Duo, President of CAICT met with Mr. Göran Marby and the delegation. After the meeting, Mr. Marby attended the Chinese Internet Community Seminar held jointly by CAICT and ICANN Beijing Engagement Center. more
Two of the hottest trends in networking today are network dis-aggregation and SDN. This is great for many reasons. It's also confusing. The marketing hype makes it hard to understand either topic. SDN has become so vague that if you ask 10 experts what it means, you are likely to get 12 different answers. Network dis-aggregation seems straightforward enough until it gets confused with SDN. We need to take a step back. In a recent Packet Pushers blog post; I start with a simple explanation of each of these trends and then map how they interact. more
With the DNSSEC Root Key Rollover coming up on October 11, how prepared are we as an industry? What kind of data can we collect in preparation? What is the cost-benefit (or not) of implementing DANE? What can we learn from an existing rollover of a cryptographic algorithm? All those questions and more will be discussed at the DNSSEC Workshop at the ICANN 62 meeting in Panama City, Panama, on Monday, June 25, 2018. more
The arrival of the iPhone, Android and iPad will raise the stakes higher in the mobile broadband market. The fact that iPhone alone has over 140,000 Apps over sort of open networks, not portals, shows the demand for mobile applications. This will put an enormous strain on the infrastructure of the mobile operators and will require them to build fibre networks to all mobile stations, as well as invest in more spectrum and new technologies such as LTE. At the same time the mobile subscriber markets are becoming saturated and competition is driving margins down. more
On September 23, ICANN's Chief Operating Officer, Doug Brent was asked by ranking members of the U.S. House of Representatives Judiciary Committee why they were continuing to move forward with the launch of new gTLDs when they had not yet been able to resolve complaints. Brent stated that Internet users have long called for the expansion of new gTLDs and that winners of new gTLDs would have to abide by a lengthy set of rules. Brent went on to say that "ICANN did not casually think this plan up." more
When I initiated NNSquad (Network Neutrality Squad), one of my primary concerns was that many seemingly reportable "events" that can occur on the Internet -- and that might seem on their face to be network neutrality "violations" -- might actually be caused by innocent technical issues related to ISP operations, testing anomalies, or misinterpretation of test or otherwise observed data. Analysis of these situations -- which may invoke security and privacy concerns -- can be quite complex, and without a reasonably complete picture of events can also be considerably problematic... more
Imagine that Ford was held responsible every time one of its Mustangs broke the speed limit. Imagine that the company responded by limiting the speed of its vehicles to 65 MPH, or that the company was required by the government to report every speeding car to highway patrol. It sounds far-fetched, but is actually a good metaphor for the way that many want technology companies to respond to infractions. more
The first 12 domain registries have been scheduled for the first special Sunrise Period mandated by ICANN for trademarks on the blocked collision lists. A total of 328 new domain extensions have launched so far in 2014. Each one of these has its own unique collision list of names that were found to be already in use on private computer networks. Some of these lists have over 100,000 names. All of these registries were required to block these names from being allocated until a policy for their allocation could be developed by ICANN. more
Community gTLDs play an interesting and even unique role in the ICANN new gTLD process. They reflect the community-driven nature of the Internet. Indeed the story of how Community gTLDs came about is a fascinating example of the how bottom-up process can give rise to innovative policy outcomes. It has been over six years since the community gTLD concept was first discussed. In the mists of time, it's easy to forget the deep foundations upon which this concept is based. more
