IPv6: A 2012 Report Card

The Gogonet Live conference in San Jose witnessed outstanding presentations by several federal administrations including Veteran Affairs, NASA and SPAWAR, sharing their experience and progress towards IPv6 adoption. Furthermore, the NIST compliance report leaves no agency any place to hide. The report card is there for everybody to see. In spite of regular jabs and criticisms, the US Federal Government has done a remarkable job. more

Google Fiber: Technology Innovation Or Revenue Assurance?

Google's announcement of its 'Fiberhoods' throughout Kansas City is yet another example of the thought leadership and innovation being brought forward by the popular advertising company. But what does this move say about the state of Internet access in America? more

IPv6: Don’t Forget About Your Switches!

When preparing a network for IPv6, I often hear network administrators say that their switches are agnostic and that there is no need to worry about them. Not so fast. Yes, LAN switches function mainly at layer 2 by forwarding Ethernet frames regardless of whether the packet inside is IPv4 or IPv6 (or even something else!) However, there are some functions on a switch that operate at layer 3 or higher. more

Google’s Secret Strategy With the Kansas City Fiber Project

I have long been perplexed at how Google plans to make a profit with their Kansas City Fiber project. Originally the project was touted as an altruistic move by Google to really understand the underlying costs of deploying fiber in a large municipality. But as anyone who has been in the trenches can tell you, it is not the technology that determines the cost of a fiber deployment, but the tyranny of the take-up. more

Occam’s ITRs

It's been a quarter of a century since the world's governments convened to draft up a common set of regulations about the conduct of international telecommunications. In December of 2012 the world's governments will convene to reconsider these regulations, to hopefully sign an updated set of regulations. This time around, this activity is generating considerable levels of public interest. Congressional hearings in the United States have been held, and various pronouncements of intent from various governmental, regional, and industry groups have been made. more

IPv4: Business As Usual

This year, we expect that the RIPE NCC's pool of unallocated IPv4 addresses will reach the "last /8", meaning that we have 16,777,216 IPv4 addresses left in the available pool. At that point it will no longer be possible for RIPE NCC members to obtain the amount of IPv4 addresses they will require to expand their current and future networks. When we hit the last /8, the RIPE NCC will only be able to distribute IPv6 addresses and a one-off allocation of IPv4 address space... Has this caused a last minute rush? more

Canadian Telcos Fast Tracking FttH to Combat Cable Operators

There are a number of stimuli which are pushing Canada's burgeoning FttH market, and the government and telcos alike have made significant steps to improve the reach and capacity of broadband infrastructure. These measures will show real benefits for consumers in recent years. From the government's side, its Economic Action Plan, launched in 2009 as a response to the global financial crisis, included a pledge to provide $225 million over three years towards its Broadband Canada Program, geared to extending broadband coverage to underserved communities. more

Growth in IPv6-Capable DNS Infrastructure

In our last post on CircleID we showed encouraging growth in the number of IPv6-enabled networks. But announcing an IPv6 prefix is only one of the first steps a network operator should take when deploying IPv6. For a full IPv6 deployment, IPv6 needs to be enabled on network infrastructure and made available to end users. One key piece of infrastructure for which we can measure IPv6 capabilities are DNS resolvers. more

The Top 3 Emerging Threats on the Internet

Last week at RSA, Bruce Schneier gave a talk on the top 3 emerging threats on the Internet. Whereas we in the security field usually talk about spam, malware and cyber crime, he talked about three meta-trends that all have the potential to be more dangerous than the cybercriminals. Here are my notes. more

MegaBust’s MegaQuestions Cloud the Net’s Future

Mid-January 2012 marked a major inflection point for digital copyright policy in the United States... Yet no one involved with Congressional interaction on either side of the issue believes it has been sidetracked for long, and "Hollywood" and "Silicon Valley" are both plotting their next moves in this high-stakes game to further define the responsibilities and potential liabilities... The resolution of this dispute will determine the ability of Internet services to move to "the cloud"... more

Cloud Computing’s Concealed Complexity

James Urquhart claims Cloud is complex - deal with it, adding that "If you are looking to cloud computing to simplify your IT environment, I'm afraid I have bad news for you" and citing his earlier CNET post drawing analogies to a recent flash crash. Cloud computing systems are complex, in the same way that nuclear power stations are complex - they also have catastrophic failure modes... more

Protecting Intellectual Property is Good; Mandatory DNS Filtering is Bad

It has been about six months since I got together with four of my friends from the DNS world and we co-authored a white paper which explains the technical problems with mandated DNS filtering. The legislation we were responding to was S. 968, also called the PROTECT-IP act, which was introduced this year in the U. S. Senate. By all accounts we can expect a similar U. S. House of Representatives bill soon, so we've written a letter to both the House and Senate, renewing and updating our concerns. more

Making Internet Faster: Google, OpenDNS and Others Announce Joint Effort

Google, OpenDNS, content delivery networks and other operators have announced a joint effort called "The Global Internet Speedup," to "make the Internet faster". According to the group, this collaboration will be executed via an open IETF proposed standard called "edns-client-subnet" in order to help better direct content to users thereby decreasing latency, decreasing congestion, increasing transfer speeds and helping the Internet to scale faster and further. more

Two Stage Filtering for IPv6 Electronic Mail

I'm a guest at the MAAWG conference in San Francisco this week and several people have now mentioned to me the problem and the opportunity of anti-spam e-mail filtering for IPv6. Tomorrow is World IPv6 Day but since a bunch of the pieces have clicked together in my head I'll post this a day early. more

Syrian Internet Shutdown

James Cowie from Renesys reports: "Starting at 3:35 UTC today (6:35am local time), approximately two-thirds of all Syrian networks became unreachable from the global Internet. Over the course of roughly half an hour, the routes to 40 of 59 networks were withdrawn from the global routing table." more
