New developments that have been announced by the FCC in the United States have rekindled the decade-old debate on the use of the so-called 'white spaces' in broadcast spectrum that are to be used for telecoms purposes. In September 2010, the FCC adopted a Second Memorandum Opinion and Order that updated the rules for unlicensed wireless devices that can operate in broadcast television spectrum at locations where that spectrum is unused by licensed services. This unused TV spectrum is commonly referred to as television 'white spaces'. The rules allow for the use of unlicensed TV devices in the unused spectrum to provide broadband data and other services for consumers and businesses. more
It is no secret that in the Caribbean people are crazy about their cell phones. In fact, the Caribbean has one of the highest levels of mobile phone penetration in the world. According to a report from BuddeComm, an Australia-based telecom research firm, mobile phone penetration in Latin America and the Caribbean reached an estimated 80% in early 2009, well above the world average which was about 58%. The report stated that Latin America and the Caribbean together now account for an estimated 12% of the world's 3.97 billion mobile subscribers. more
The growing interest in the "Internet of Things" is forcing us to think beyond the web to a much larger world of connected devices. We can tolerate the many barriers to connectivity because we expect that someone can provide the necessary credentials to log in to the providers' services and to adjust Wi-Fi access keys whenever the access point changes or simply to click "agree" at a hotspot. This doesn't work for "things" which can't recognize a sign-on or "agree screen". more
In the last few years there have been many discussions on how the Internet is governed, and how it should be governed. The whole World Summit on the Information Society (WSIS) ended talking about this problem. It caused exchange of letters between the US Secretary of State and the European Union presidency. And it caused a public discussion, organized by the US Department of Commerce on that issue. I saw some reflection of this discussion and here are some comments on that. My colleague Milton Mueller of the Syracuse University sent me an e-mail today in which, among other, it says, "A global email campaign by IGP generated comments from 32 countries... more
I've always been a fan of co-ops. In New York, we shop at greenstar.coop and my wife banks at alternatives.coop, in the UK we shop at co-operative.coop. So when the .COOP domain opened, I wondered if I could get my own clever domain name, but found that chicken.coop was taken by a small producer co-op in the southern U.S. Drat. more
There have been a number of attacks on the root name servers over the years, and much written on the topic. (A few references are here, here and here.) Even if you don't know exactly what these servers do, you can't help but figure they're important when the US government says it is prepared to launch a military counterattack in response to cyber-attacks on them. more
Despite global polarization, recent UN cyber diplomacy has achieved three significant agreements in 2024: a cyber attack reporting system, a convention against cybercrime, and a "Global Digital Compact." These successes show that consensus on global issues is possible, though the vague wording of agreements raises concerns about their long-term effectiveness in ensuring security and peace. more
This week's myth is interesting because if we weren't talking security it wouldn't be a myth. Say what? The phrase "96 more bits, no magic" is basically a way of saying that IPv6 is just like IPv4, with longer addresses. From a pure routing and switching perspective, this is quite accurate. OSPF, IS-IS, and BGP all work pretty much the same, regardless of address family. Nothing about finding best paths and forwarding packets changes all that much from IPv4 to IPv6. more
Over the course of the last week, ICANN has released several pieces of information that taken together begin to allow us to piece together the overall gTLD landscape. ICANN is releasing partial information, without explanation or context, in dribs and drabs, and rumors are flying that we won't get the "Reveal" until the ICANN meeting in Prague at the end of June. This partial information and delay from ICANN is creating consternation and confusion among the many applicants and those watching the new gTLD scene. more
The .net Top Level Domain (TLD) contains the names of the main group of DNS root servers as well as the names of the servers for several other large TLDs, such as .com, .org, .arpa and .mil. Most of the focus about the .net redelegation has concerned the quality of the registration systems. But that is a minor matter next to the quality of the name server operation. more
You all remember cybersquatting, a popular sport in the late 90s, right? McDonalds.com, JenniferLopez.com, Hertz.com and Avon.com thankfully all point to the right web sites today, but thaiairline.com, mcdonald.com, luftansa.com, gugle.com, barnesandnobles.com and other misspellings are fake web sites intended to trap the casual surfer with a hand that's a bit too much quicker than the eye... If you want to go to the McDonalds web site, you don't even spend the 10 seconds to look it up -- you will type McDonalds.com and expect to see the latest dollar meal menu. But the same is true for the other popular form of communication -- email... more
In my department, we block about 92% of our total email (around 2.5 billion per day) at the network edge without accepting the message. When we do that, we don't see any traffic from that IP anymore and don't keep stats on it due to the overwhelming volume of mail. However, we do keep stats on mail that we block with our content filter. I decided to go and calculate how much spam we receive from each country by mapping the source IP back to its source country... more
Hot on the heels of other ICANN Internationalized Domain Name (IDN) Top-Level Domain (TLD) launch errors, we now have another example of ICANN's failure to comprehend the differences between IDN and ASCII names, this time to the detriment of potential IDN registrants and the new IDN generic TLD (gTLD) Registries. This gaff really makes you wonder whether the SSAC and Multilinguism departments at ICANN have ever met. more
25 years ago, on April 22, 1993, a software release happened that fundamentally changed the user experience of the Internet. On that day, version 1.0 of "NCSA Mosaic for the X Window System" was released. You could now have (gasp!) text MIXED WITH IMAGES on the same page! Reading the Mosaic 1.0 release notes from Marc Andreessen is a bit of fun, as it includes gems like "Fixed mysterious stupid coredump that only hits Suns." more
I'm curiously puzzled, but not entirely surprised, how a company such as Amazon (NASDAQ: GS) allowed its servers to be interrupted for any length of time due to severe storm damage in northern Virginia this past weekend. Companies using cloud servers are both expectant and dependent on being able to pull information from cloud sources to operate their businesses without interruption. After all, IT professionals have been preaching the security and reliability of the cloud for quite some time to manage large data off-site. Steps for Amazon to repair credibility should be transparent and swift. more
