It's common to hear that oversubscription is the cause of slow broadband -- but what does that mean? Oversubscription comes into play in any network when the aggregate subscribed customer demand is greater than the available bandwidth. The easiest way to understand the concept is with an example. Consider a passive optical fiber network where up to 32 homes share the same neighborhood fiber. more
Technical development often comes in short, intense bursts, where a relatively stable technology becomes the subject of intense revision and evolution. The DNS is a classic example here. For many years this name resolution protocol just quietly toiled away. The protocol wasn't all that secure, and it wasn't totally reliable, but it worked well enough for the purposes we put it to. more
For nearly the past four years, the Trump Administration has purported to treat 5G supply chain security through empty political gestures such as network equipment banning. The disinformation reached its absurd zenith subsequent to the election with the Q-Anon myth of the Kraken. (The Myth advanced by Trump attorneys asserted the long-deceased Hugo Chavez working with China was corrupting voting machine software to deprive Trump of another term.) more
The Internet has enhanced freedom of communication, ignored national borders, and removed time and space barriers. But the Internet sphere was never a law-free zone. Already ICANN's "Articles of Incorporation" (1998) constituted that the management of critical Internet resources has to take place within the frameworks of "applicable national and international law". more
As 2020 draws to a close, it becomes possible to assess the trends from different policy areas that were most impacted by the global pandemic, with health-related policies rising to the top of that list. This article focuses on the sale of medicines using the Internet, as it should, without a doubt, be one of the leading concerns of both the general public and policymakers. There is a disconcerting lack of broader social debate around the subject, even though the need is so great. more
Are there any companies left that we can still call cable companies? Everything in the business press still refers to Comcast and Charter as cable companies and AT&T and Verizon as telephone companies. It's getting harder to justify using these traditional labels, and maybe the time is finally here to just start calling them all ISPs. After all, these four companies collectively have 80 million broadband customers... more
There is a new threat in town known as "SAD DNS" that allows attackers to redirect traffic, putting companies at risk of phishing, data breach, reputation damage, and revenue loss. What is SAD DNS? No, it isn't the domain name system (DNS) feeling moody, but an acronym for a new-found threat -- "Side-channel AttackeD DNS" discovered by researchers that could revive DNS cache poisoning attacks. more
Over the past several years, questions about how to protect information exchanged in the DNS have come to the forefront. One of these questions was posed first to DNS resolver operators in the middle of the last decade, and is now being brought to authoritative name server operators: "to encrypt or not to encrypt?" It's a question that Verisign has been considering for some time as part of our commitment to security, stability and resiliency of our DNS operations and the surrounding DNS ecosystem. more
We are suffering an epidemic of cyberattacks while in a viral pandemic. This post is for those who have responsibility for assuring that the IT-based services offered by their enterprise can quickly recover in the case of successful cyber-attack or other disaster. University of Vermont Medical Center (UVMMC) is an excellent hospital. I owe my life to treatment there and am grateful for both the skill and the kindness of UVMMC staff. They have been devastated by a cyber-attack. more
The Internet of Things (IoT) is on an explosive growth trajectory. According to Transforma Insights, the number of IoT-connected devices is projected to increase to 24.1 billion worldwide by 2030. That's almost a three-fold increase from 2019. Much of this growth will be fueled by the coming 5G revolution, which will enable businesses and consumers to take advantage of a wide range of increasingly sophisticated connected devices. more
Verisign is deeply committed to protecting our critical internet infrastructure from potential cybersecurity threats, and to keeping up to date on the changing cyber landscape. Over the years, cybercriminals have grown more sophisticated, adapting to changing business practices and diversifying their approaches in non-traditional ways. We have seen security threats continue to evolve in 2020, as many businesses have shifted to a work from home posture due to the COVID-19 pandemic. more
Internet Governance, like all governance, needs guiding principles from which policy making, and acceptable behavior, are derived. Identifying the fundamental principles to guide Internet ecosystem policy making around digital citizenship, and around the integrity of digital practices and behavior, can and should start with the Universal Declaration of Human Rights, (UDHR). more
You can't put the telecom sector into perspective without looking at the performance of the biggest players in the industry. The pandemic has been an interesting year for both big ISPs and telecom vendors. Smaller ISPs should care about big ISP performance for many reasons. For many smaller companies, the big companies are the competition, and the big providers' strength or weakness can foretell stiffened competition or increased opportunity. more
A recent session of the Australian Computer Society (ACS) and the Australian Smart Communities Association (ASCA) masterclass on 5G, featured Dr. Ian Oppenheimer, the NSW Government's Chief Data Scientist and one of the country's most respected experts in radio technology. Ian is also the Chair of the scientific advisory board of the 6G Flagship organization, a global research organization based in Finland. This organization has just published a range of fascinating research papers on 6G. more
In a publication released on October 2, 2020, RIPE NCC reported its first seizure of IPv4 registration rights pursuant to a Dutch court order. Pursuant to the order, RIPE NCC effectuated a transfer of the IP Addresses from the liquidating debtor to its creditor. Although these IP Addresses could not be owned, they were apparently not legacy. Thus, they conferred no "property rights" - the registration rights were deemed an enforceable right that has value and were to be utilized towards satisfaction of a judgment. more
