Qtel, the largest carrier in Qatar (and nearly the only Internet provider) appears to connect all their users (~600K) to the Internet through just one or a very few public IPv4 addresses. 82.148.97.69 was their single public address in 2006-2007. How can network address translation (NAT) put all those users through just one IP address? more
The rise of the Internet has heralded rapid changes in our society. The opportunities presented by a capable and ubiquitous communications system and a global transportation network have taken some corporations from the multinational to the status of truly global mega-corporation. Good examples of these new corporations include Google, Apple, Amazon, Microsoft and Facebook. There are a handful of large-scale winners in this space and many losers. But this is not the first time we've witnessed a period of rapid technological and social change. more
The Federal Communications Commission (FCC) today approved, in a 5-0 unanimous vote, the plan to open up unused, unlicensed portions of TV white space spectrum for wireless applications and devices. However, to prevent interference, FCC has also placed some "rigorous certification process" which device offered by a technology company for use on the white spaces will have to go through. more
Vectoring is an extension of DSL technology that employs the coordination of line signals to reduce crosstalk levels to improve performance. It is based on the concept of noise cancellation: the technology analyses noise conditions on copper lines and creates a cancelling anti-noise signal. While data rates of up to 100Mb/s are achievable, as with all DSL-based services this is distance related: the maximum available bit rate is possible at a range of about 300-400 meters. more
I buy a lot of things that are delivered by UPS or FedEx. And I kinda like to watch the progress of the shipments. Now we all know that UPS and FedEx have different grades of service -- Overnight, Two Day, Three Day, etc. And faster deliver costs more. Several years ago UPS and FedEx would frequently deliver a Two Day package the next day, i.e. they would effectively elevate the class of service. more
On August 14 at 11 AM ETECSA, Cuba's monopoly ISP, began a 9-hour, nationwide test of 3G mobile Internet access -- anyone near a 3G-equipped cell tower with a compatible phone and a prepaid mobile telephony account could get free access until 8 PM. As far as I know, the only notification was this post on the ETECSA Facebook page, but word of the test and instructions for getting online spread by word of mouth. more
"What Will the Internet of the Future Look Like?," was the subject of a panel discussion held this week in Washington, DC, organized by the Information Technology & Innovation Foundation (ITIF). The discussion was aimed at examining pending Internet regulations in the U.S. and their impact on packet discrimination, traffic shaping, network management, and carrier business models. The panel, moderated by Robert Atkinson, included: Richard Bennett; Dr. David Farber; Charles Jackson; and Jon Peha. more
If a national government wants to prevent certain kinds of Internet communication inside its borders, the costs can be extreme and success will never be more than partial. VPN and tunnel technologies will keep improving as long as there is demand, and filtering or blocking out every such technology will be a never-ending game of one-upmanship. Everyone knows and will always know that determined Internet users will find a way to get to what they want, but sometimes the symbolic message is more important than the operational results. more
Declan McCullagh reporting in CNET: "The FBI is asking Internet companies not to oppose a controversial proposal that would require the firms, including Microsoft, Facebook, Yahoo, and Google, to build in backdoors for government surveillance. In meetings with industry representatives, the White House, and U.S. senators, senior FBI officials argue the dramatic shift in communication from the telephone system to the Internet has made it far more difficult for agents to wiretap Americans suspected of illegal activities..." more
The business world today features many complex global service activities which involve multiple interconnected service providers. Customers normally expect to execute a single paid transaction with one service provider, but many service providers may assist in the delivery of the service. These contributory service providers seek compensation for their efforts from the initial provider. However, within a system of interdependent providers a service provider may undertake both roles of primary and contributory provider, depending on the context of each individual customer transaction. more

We shouldn't settle for network neutrality. It's a poor substitute for what we had and much less than what we need. Let me explain. There are two topics to discuss. The first is "common carriage," a centuries old legal concept that applied to the US telecom industry throughout most of the 20th century. The second involves communications protocols. Both topics are complex, so I will cover only what's needed to understand why we shouldn't accept network neutrality and why, at a minimum, we should fight for enforcement of existing common carriage rules. more
The recent NANOG 61 meeting was a pretty typical NANOG meeting, with a plenary stream, some interest group sessions, and an ARIN Public Policy session. The meeting attracted some 898 registered attendees, which was the biggest NANOG to date. No doubt the 70 registrations from Microsoft helped in this number, as the location for NANOG 61 was in Bellevue, Washington State, but even so the interest in NANOG continues to grow... more
Larry Seltzer writes: Politico? Comcast's PR gets an 'A' for this article, an upbeat tech-lite description of the impending depletion of the IPv4 space and efforts to adopt IPv6. It also seems that the Obama administration is behind this, and that the Federal government has had "remarkable foresight on this issue." I feel better already. more
Moore's Law explains why the price of everything electronic keeps going down; but now Moore's Law is starting to have an effect on much more than technology prices. The costs of energy, medicine, law, education, financial transactions, and government itself are falling because of Moore's Law's relentless progress. But these cost decreases are not being fully reflected in the prices we pay for all these things. more
