Blocking Amplification Attacks: Sometimes the Incentives Work Against You

Since the end of last year, amplification attacks have been increasingly used by attackers and received heavy media coverage. Everyday protocols not given much thought before, like Network Time Protocol (NTP), can be asked in a very short remote command to send a very large response (list of 600 clients last connected to the NTP server) to a spoofed IP address (the target) by the requestor/attacker. more

NTAG Chair Blog: Odds and Endings

Imagine if the US Bureau of Labor Statistics delayed one of its reports for say, two months. No explanation. Just didn't release the employment numbers when it said it would. What if the Federal Reserve decided to say it was going to raise interest rates, but then just didn't? The global economy would be thrown into chaos. These organizations know that when you run critical infrastructure your word is part of that infrastructure. more

The US-China Cold War in Cyberspace

In 2019 and 2020, the economic conflict between the US and China reached a peak. There was a months-long tariff battle that is still not fully resolved. After blocking Chinese-centered equipment manufacturer Huawei from its own markets, the US pushed hard to get the Five Eyes and all of its allies to block Huawei from foreign markets, too. Then the US started blocking its own companies... more

Three Views of Multistakeholder Leadership in the Age of Sovereignty

As multistakeholder governance nears a critical juncture, leaders must navigate diverging views, geopolitical pressures and technological upheaval. With sovereignty concerns mounting, the Internet's institutions face a complex future that demands deft stewardship. more

Traditional Big ISPs Stagnate

In the first quarter of this year, the big cable companies added 482,000 customers, while telcos added over 50,000 customers. In what is a surprise to the industry, that growth has disappeared, and all of the big ISPs collectively lost almost 150,000 customers. That's a loss of 60,000 customers for the cable companies and 88,000 for the big telcos. The following statistics have been compiled by the Leichtman Research Group, which tracks the broadband performance of the largest ISPs in the country. more

The Growth Rate of Broadband Speeds

Cisco has changed the name of its periodic predictions of broadband usage from the Visual Networking Index to the Annual Broadband Report, and recently issued a report that covers the period from 2018 to predictions made through 2023. Cisco is one of the few industry players that projects future broadband usage. Their past reports have been spot on in terms of predicting future broadband usage. more

The Growth of DNS-OARC Highlights Great Strides in DNS Research

This past weekend several of my Dyn colleagues and I attended the DNS-OARC annual meeting and fall workshop in Montreal. "OARC" in the organization's title stands for "Operations, Analysis and Research Center". DNS-OARC was founded by the Internet Systems Consortium (best known as the maintainers of the BIND DNS software) in 2004 to address a gap in the DNS community. Engineers working to extend the DNS protocol itself have always had a home in the Internet Engineering Task Force (IETF), but there was no corresponding community for those who operated DNS infrastructure and did research using data gleaned from DNS operations. more

The Security Talent Gap Is Misunderstood and AI Changes It All

Despite headlines now at least a couple of years old, the InfoSec world is still (largely) playing lip-service to the lack of security talent and the growing skills gap. The community is apt to quote and brandish the dire figures, but unless you're actually a hiring manager striving to fill low to mid-level security positions, you're not feeling the pain -- in fact, there's a high probability many see problem as a net positive in terms of their own employment potential and compensation. more

Is There a Business Case for Fast Cellular?

We've gotten a glimpse of the challenges of marketing faster cellular usage since the two major cellular providers in South Korea made a big push in offering ultrafast cellular broadband. South Korea has two primary cellular carriers – SK Telecom and KT – and both have implemented cellular products using millimeter wave spectrum in Seoul and other dense urban areas. more

The Huawei Issue in the Broader Context of Global Politics

It is very sad to see that Huawei has become a victim of US-China trade war politics and it will be very interesting to see how their court case against the US Government will pan out, the company claims that the ban of its products is "unconstitutional." There is no indication that Huawei has been involved in any spying activity; nor does it appear to have any intention of doing so. more

Do Not Track: Not as Simple as it Sounds

Over the past few weeks, regulators have rekindled their interest in an online Do Not Track proposal in hopes of better protecting consumer privacy. ... There are a variety of possible technical and regulatory approaches to the problem, each with its own difficulties and limitations, which I'll discuss in this post. more

Pinpointing Urban Broadband Gaps

The City of Chicago asked some researchers at the University of Chicago for help to identify the neighborhoods and the number of households that are not connected to broadband. It's been well known that large numbers of people in cities don't have broadband, but there have been no easy ways to pinpoint where solutions are needed. more

IANA Transition is Just the Beginning

The transition of the Internet Assigned Numbers Authority (IANA) functions is finally in the history books. After almost two years of working groups and multiple rounds of meetings, most of us want to take a long vacation and never hear the acronym "IANA" again. However, the transition is just the beginning. Now is the time for the multistakeholder community to exercise its new authorities and responsibilities to ensure ICANN remains accountable to every internet user. more

Can Cellphones Capture the Broadband Market?

Linda Hardesty wrote an interesting article in FierceNetwork that asks the question, "What if, in ten years, young people don't subscribe to fixed broadband at all?" Her story is based on a U.K. research group that predicts that within ten years, there will be a lot of young people who will never have subscribed to a landline broadband product. more

Want to Help Guide the Future of the MANRS Routing Security Initiative?

Would you like to help guide the future of the Mutually Agreed Norms for Routing Security (MANRS) initiative? As the MANRS community continues to develop new efforts to make the routing layer of the Internet more secure (ex. the equipment vendor program), would you like to help lead the work? The MANRS community is seeking volunteers for its new Steering Committee. The committee will lead the community as it evolves its governance model.  more
