.PARIS : Can the Backend Registry Help Sales?

As published on June 24, 2025, it is with no surprise that the AFNIC was renewed as the backend registry provider of the .PARIS new generic Top-Level Domain. What caught my attention in the announcement was this paragraph: “Afnic’s remit will also be expanded to include communication and promotion of the .paris TLD, as well as the development of initiatives designed to increase its adoption by businesses and private individuals.” more

An Overview of the Concept and Use of Domain-Name Entropy

In this article, I present an overview of a series of 'proof-of-concept' studies looking at the application of domain-name entropy as a means of clustering together related domain registrations, and serving as an input into potential metrics to determine the likely level of threat which may be posed by a domain. more

The BIG Impact: How Cloud Computing is Changing the Face of Small Business

While 86 percent of small businesses see the importance of the cloud, 70 percent aren't using cloud solutions. This data, from a Microsoft report for National Small Business Week and reported by Talkin' Cloud, yields a sobering conclusion: Small businesses understand the broad value of cloud computing, but aren't sure how to apply the technology on a case-by-case basis. more

What Became of the ARCOS Undersea Cable Connection to Cuba?

Cuba's primary connection to the global Internet is through the ALBA-1 undersea cable linking landing points on the south-east shore of the island to Venezuela and Jamaica; however, the bulk of Cuban traffic originates in Havana which is on the north-west coast. Traffic from Havana and other cities in the west travels over a backbone to reach the cable landing points. A landing point near Havana would reduce the load on the backbone... more

DPI is Not a Four-Letter Word!

As founder and CTO of Ellacoya Networks, a pioneer in Deep Packet Inspection (DPI), and now having spent the last year at Arbor Networks, a pioneer in network-based security, I have witnessed first hand the evolution of DPI. It has evolved from a niche traffic management technology to an integrated service delivery platform. Once relegated to the dark corners of the central office, DPI has become the network element that enables subscriber opt-in for new services, transparency of traffic usage and quotas, fairness during peak busy hours and protection from denial of service attacks, all the while protecting and maintaining the privacy of broadband users. Yet, DPI still gets a bad rap... more

Securing a Domain: SSL vs. DNSSEC

There has been quite a bit of talk lately about the best way to secure a domain, mainly centered in two camps: using Secure Socket Layer (SSL), or using DNS Security Extensions (DNSSEC). The answer is quite simple -- you should use both. The reason for this is that they solve different problems, using different methods, and operate over different data. more

Squirrels Are the Number One Culprit for Animal Damage to Aerial Fiber

These cute rodents are the number one culprit for animal damage to aerial fiber. To a lesser degree, fiber owners report similar damage by rats and mice. Squirrels mainly chew on cables as a way to sharpen their teeth. Squirrel teeth grow up to 8 inches per year and if squirrels aren't wearing their teeth down from their diet, they look for other things to chew. more

You Don’t Need to Hack Twitter.com to Control All Its Traffic and Email

A big security news event last night and today is that the Twitter.com Web site was hacked and content on the site replaced. TechCrunch reported it and it has been picked up globally. But - was the Twitter.com website really hacked? We now know it was not so. There are four ways that users typing in Twitter.com would have seen the Iranian Cyber Army page. more

700 MHz Auction Winners: Why Block C Matters

Today the FCC announced the winners of the 700 MHz auction -- and you can see from pp. 62-63 of this document that Verizon won Block C. (Block C was set up in two nationwide paired blocks of 11 MHz each, which were auctioned off in very large geographic areas -- 12 licenses, each covering a "Regional Economic Area Grouping". Verizon won seven of the twelve licenses, covering all of the US except Alaska, Puerto Rico, American Samoa, Guam, and the Northern Mariana Islands.) Why does this matter? more

Why Do We Care About Names and Numbers?

An article based on the most recent study for the European Commission on the Policy Implications of Convergence in the Field of Naming, Numbering and Addressing written by Joe McNamee and Tiina Satuli of Political Intelligence.

"With relation to the Internet and also IP addresses, the "scarcity" is more complicated: there are not only intellectual property issues with regards to domain names, but there is also an issue of managing the integrity of the system. For any naming or numbering system to work, it is essential that the names and addresses used cannot be confused with any other -- in other words, no one system can have two end-points with the same fully qualified number or name..." more

ICANN Should Curb Anonymous Domain Name Abuses

E-commerce has revolutionized how businesses sell to consumers -- including those involved in illicit activities, such as websites peddling illegal narcotics, pirated movies and music, or counterfeit handbags. For example, 96 percent of Internet pharmacies do not comply with U.S. laws, and as they ship pills tainted with paint thinner, arsenic, and rat poison, they put the health and safety of consumers at risk. Why don't law enforcement officials do more to combat this problem? Partly because of the difficulty of identifying who is actually operating the illegal pharmacies. It is time to fix this, while allowing anonymity for those who deserve it. more

Digging Into IPv6 Traffic to Google: Is 28% Deployment Really the Limit?

After some years of accelerating IPv6 deployment, we are now into a period of slower growth and it's not clear where we are heading. It is therefore interesting to try to predict the future of IPv6 over the coming years. At Ericsson Research, we have been working on this topic since 2013, but just recently created a forecast model that seems to be quite accurate. However, it gives a disappointing message of a very low final level of IPv6 deployment at less than 30%! more

Are We Ready for Big Bandwidth Applications?

There is a recent industry phenomenon that could have major impacts on ISP networks in the relatively near future. There has been an explosion of households that subscribe to gigabit data plans. At the end of 2018, only 1.8% of US homes subscribed to a gigabit plan. This grew to 2.8% by the end of 2019. With the pandemic, millions of homes upgraded to gigabit plans in an attempt to find a service that would support working from home. more

New Research from CSC on the Impact of COVID-19 on Internet Security and Safety

Hackers are using company domain names for malicious attacks more than ever before. Established research shows that phishing and related malware attacks most commonly occur from a compromised or hijacked legitimate domain name, a maliciously registered, confusingly similar domain name, or via email header spoofing. Domain security intelligence is the first line of defense in preventing domain cyberattacks. more

ITU Launches IDN Survey and ccTLD Outreach

Today, the ITU launched a new survey asking member states, ccTLDs and other ITU member organizations to provide answers to a specialized questionnaire asking for their experiences on the use of IDNs. The ITU states that it is reaching out to ccTLDs to "collect information and experiences on Internationalized Domain Names under ccTLD (country code Top Level Domain) around the globe." One of the goals of this survey is to collate information on the "needs and practices" of each ccTLD that is surveyed -- so as to compile a report from the ITU that speaks to the implementation of IDNs around the world... more
