In the move towards enabling mobile devices to use TV white spaces spectrum, Google along with Comsearch, Dell, HP, Microsoft, Motorola, and Neustar today announced the launch of White Spaces Database Group. The creation of this database has been part of FCC's big vote and approval of white spaces for broadband back in November. This is a required measure to ensure devices can locate channels and avoid interference. more
The complicated events surrounding the African Network Information Centre (AFRINIC) were brought to light this week by ARIN's President and CEO John Curran during a recent presentation followed by a report today by Simon Sharwood of The Register. more
I'm in the camp that ICANN Top-Level Domains (TLDs) are businesses that should be allowed to evolve from their original charter to increase their viability in the marketplace. It was announced today that VeriSign is proposing to allow telephone numbers and other numeric identifiers in the .NAME top-level domain. This could be the Killer App that ENUM has been waiting for. more
There are some real problems in DNS, related to the general absence of Source Address Validation (SAV) on many networks connected to the Internet. The core of the Internet is aware of destinations but blind to sources. If an attacker on ISP A wants to forge the source IP address of someone at University B when transmitting a packet toward Company C, that packet is likely be delivered complete and intact, including its forged IP source address. Many otherwise sensible people spend a lot of time and airline miles trying to improve this situation... The problems created for the Domain Name System (DNS) by the general lack of SAV are simply hellish. more
As many of you know, I'm launching the Emerging Communications (eComm) conference -- taking place next month in Silicon Valley, at the Computer History Museum. Communications innovation has been stagnant, in my opinion, for nearly a decade. Telecommunications and Internet communications both seem to be at somewhat of an impasse. The communications industry needs a forum to help break through the stagnancy and highlight the huge opportunity space that is emerging. The stagnancy has been strikingly more so in telecommunications... more
A long time ago in an Internet far away, nobody paid for DNS services. Not directly at least. We either ran our own servers, or got DNS service as part of our IP transit contract, or traded services with others. In ~1990 I was the operator of one of the largest name servers in existence (UUCP-GW-1.PA.DEC.COM) and I exchanged free DNS secondary service with UUNET. Two thousand zones seemed like a lot of zones back then -- little did we dream that there would some day be a billion or so DNS zones world wide. more
A revolution is taking place on the Internet, with new sites redefining how we interact online. The next-generation Internet is emerging in collaborative and interactive applications and sites with rich, varied media (images, video, music). As with many revolutions, this one is driven by the younger generation, which is adopting social networking sites like MySpace and video sharing sites like Google's YouTube. But the general shift is not restricted to the young, as more mature consumers and businesses alike are exploring the possibilities of collaborative, media-rich applications. This major shift in Internet applications has its unintended victims. One of them turns out to be the Domain Name System (DNS). more
After much initial fanfare a couple of years ago ENUM has matured to a state where it is currently yet another under-achiever in the technology deployment stakes. ENUM initially presented itself as a very provocative response to the legacy telco position of monopolising public voice services through their exclusive control over the Public Switched Telephone Network (PSTN) and the associated controlling position over the telephone number space... The perception was that ENUM was going to dismantle these levers of control and open up the voice market to a new wave of competitive carriers. If the address plan was the key to the PSTN, then ENUM was intended unlock this network and position the new wave of Voice Over IP (VOIP) carriers to take over any residual treasures of the traditional voice market. Events have not played out according to these expectations... more
In modern society, there is one fact that is unquestionable: The hyper-connectivity of the digital economy is inescapable. A financial institution without an online presence or omni-channel strategy will cease to be competitive. Universities (for-profit or non-profit) must develop and continuously evolve their online learning capabilities if they are to stay relevant. Online retailers are quickly outpacing and rendering their 'brick-and-mortar' counterparts irrelevant. more
An Analogy: Europe is to the US controlled GPS as Europe is to the US controlled DNS root? That's not a very good title is it? But it does express the point I want to make. This week the European Union launched the first satellite of its own global positioning system, Galileo. One has to wonder why the Europeans feel they need to do this. Isn't the GPS system run by the United States a perfectly good system? more
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
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
I'm writing this in response to the myriad discussions about how to make sure that the Internet continues to "work" despite P2P or whatever the current threat seems to be. Behind much of the discussion is the presumption that the Internet has a purpose in the sense of making some applications like video games and VoIP work. Yesterday we feared modems, today we fear P2P. more
In mid-March, the group dubbed by Wired Magazine 20 years ago as Crypto-Rebels and Anarchists - the IETF - is meeting in London. With what is likely some loud humming, the activists will likely seek to rain mayhem upon the world of network and societal security using extreme end-to-end encryption, and collaterally diminish some remaining vestiges of an "open internet." Ironically, the IETF uses what has become known as the "NRA defence": extreme encryption doesn't cause harm, criminals and terrorists do. more
This is an issue of some concern and should be watched carefully: phishers are now trying to get passwords of domain registrants (domain owners). Currently, correspondents inform me that GoDaddy is the target, but there's no reason to think the phishers won't expand to other registrars. Normally, phishers go after bank accounts or other financial information, or sometimes the online accounts of users so that they may send spam. It's not known precisely why phishers are after domain registration information, but the possibilities are chilling... more
