The Strange Structure of ISP Service Semantics

I have been having a number of conversations recently with several clients and colleagues about "semantics". It's clear that there is not a lot of clarity on this philosophical subject! Whilst is may be an obscure issue, it is a very important one. Our ideas lead us to take actions, and if we want those actions to have the consequences we had in mind, then we need to have done our epistemological homework. more

Newer Cryptographic Advances for the Domain Name System: NSEC5 and Tokenized Queries

In my last post, I looked at what happens when a DNS query renders a "negative" response -- i.e., when a domain name doesn't exist. I then examined two cryptographic approaches to handling negative responses: NSEC and NSEC3. In this post, I will examine a third approach, NSEC5, and a related concept that protects client information, tokenized queries. The concepts I discuss below are topics we've studied in our long-term research program as we evaluate new technologies. more

Implications of Satellite Being Broadband

We've had a quiet policy change in the United States over the last year, where satellite broadband is starting to be considered broadband by the federal government. Any rural household that subscribes to and loves Starlink would wonder why this is news, but from a policy perspective, it is a big deal. I've been considering what this shift might mean in the future. The FCC decided that Starlink wasn't broadband when it rejected Starlink's long-form filing in August 2022, where Starlink wanted to claim the funding it had won in the RDOF reverse auction.  more

EURid Updates Post-Brexit

Brexit will impact many things. One that has not been getting much attention, however, is domain names and more specifically .eu domains. Under the current regulations, you need to be a resident of the European Union to register a .eu domain name. As I covered in a blog post last year, there is the potential for hundreds of thousand of .eu domain names being pulled overnight. more

Oral History of the Early Days of ICANN: A Perspective From Europe

Essentially everyone in the computing field has heard how the creation of ICANN absolutely changed the development of the Internet and the organization of the Domain Name System (DNS). Consequently, the growth of ICANN promoted the deliberation about New Internet Trends. The blog is structured as an interview with Eugenio Triana who was one of ICANN's nine initial directors in October 1998. more

When a Domain Name Dispute is ‘Plan B’

While having a backup plan is usually a good idea, it's often not an effective way to obtain someone else's domain name - at least not when Plan B consists of a company filing a UDRP complaint with the hope of getting a domain name to which it is not entitled and could not acquire via a negotiated purchase. "Plan B" as a derogatory way of describing an attempted domain name acquisition usually arises in the context of a domain name that is not protected by exclusive (or any) trademark rights, or where the complainant clearly could not prevail in a UDRP proceeding. more

Kleinwaechters Treasure Map

Wolfgang Kleinwaechters Internet Governance Outlook on CircleID each year sums up the drama of internet governance as it is played out on the global stage. We assume that all players on the internet governance stage work under the premise that despite all our differences, ultimately, we are united in our quest for "freedom from fear and want" based on the quality and dignity of all human beings, as expressed in the Universal Declaration of Human Rights (UDHR). more

Battling Cyber Threats Using Lessons Learned 165 Years Ago

When it comes to protecting the end user, the information security community is awash with technologies and options. Yet, despite the near endless array of products and innovation focused on securing that end user from an equally broad and expanding array of threats, the end user remains more exposed and vulnerable than at any other period in the history of personal computing. more

Taking It to the Streets

It is interesting to see telecommunications policy issues being covered by the general media. Of course, we expect to see coverage of communications issues in the business press. The sector is a large employer, makes massive investments in infrastructure and virtually every citizen buys communications products and services every month. Still, covering the sector in the business section is different from seeing coverage move to the front page or the general editorial pages. more

Password Policies Need to Be the Same if We Want Users to Take Our Advice

The other day on Facebook, one of my friends mentioned that today (i.e., that day) was a good day to update his passwords. But he then lamented that some web sites don't allow you to create more than a 12-character password! He was incensed! Well, maybe not incensed but showed contempt for the fact these sites restricted password length. more

Will Broadband Go Wireless?

For years it's been impossible to go to any industry forum without meeting a few folks who predict that residential broadband will go wireless. This buzz has accelerated with the exaggerated claims that fast 5G broadband is right around the corner. I've seen even more talk about this due to a recent Pew poll that shows that the number of people that only use their cellphones for data has climbed significantly over the last few years – I'm going to discuss that poll in another upcoming blog. more

Why Homegrown Subscriber ID Solutions Limit Problem Solving

Most service providers are aware that there needs to be a simple, fast way to identify subscribers. Unfortunately, in reality, mapping IP addresses back to subscribers for identification purposes - such as lawful interception requests or acceptable use policy violations - can be complicated. It usually involves analyzing data sets, completing manual audits, or reliance on multi-step solutions. more

Highlights from ICANN67 Public Forum – Community Dialogue on Proposed Transfer of PIR Ownership

Ethos CEO Erik Brooks and I are grateful to ICANN for hosting this important community dialogue on the future of PIR and .ORG earlier this week, and we listened intently to the questions posed. To echo what John Jeffrey said in his opening remarks, we are very interested in the community's input. We appreciate the openness and candor that was expressed during the Public Forum, and we would like to take this opportunity to recap a few of the overarching themes and questions asked. more

An Internet Infrastructure Perspective on AI Service Provision

This study analyzes the differences in domain name and IP address strategies among a number of current mainstream artificial intelligence (AI) service providers. We find that these technical choices not only reflect deployment decisions but also deep-seated corporate knowledge and capabilities in Internet infrastructure service provision, as well as brand positioning and market strategies. more

NTAG Chair Blog: The Road Ahead

The next six months will be a pivotal period in ICANN & New gTLD applicant relations. April 2014 will mark one year since the Governmental Advisory Committee - better known as the GAC - issued advice that put nearly 400 applications on hold. The Name Collision issue, while no longer a gate for many applicants, currently puts thousands of second level domain names on hold. March will be a key inflection point for this issue as well. more
