2% of All Traffic to Google Now Over IPv6! (Doubling in Past Year)

This weekend brought the great news that Google's IPv6 statistics have shown that connections over IPv6 to Google's web sites hit the 2% threshold for the first time. (You can see for yourself.) While 2% sounds tiny, as I wrote in a Deploy360 post today, the important fact here is that this represents a doubling of IPv6 traffic to Google over the past year! more

Mobiles Moving Into Fixed Networks

There are often confused reports in the media about mobile and fixed broadband, with arguments that one could replace the other. Yet the reality is that they coexist and complement each other - perhaps even more so since one cannot manage without the other. Increasingly, devices such as smartphones, tablets and smart TVs are at the end of fixed lines, with a wireless (WiFi) connection between the fixed line and the device. more

Name Collision: Why ICANN Is Looking at It the Wrong Way (Part 1)

ICANN has, once again opened up a veritable can of worms, with their latest decision on the 'horrors' of Name Collision. While we are sure that ICANN and the Interisle Consulting Group have very good reason to make the decision that they have - delaying the delegation of several TLDs - we believe that the findings contained in Interisle's report do not give sufficient cause to delay the new gTLD program in the manner proposed by ICANN staff. more

DNS Amplification Attacks: Out of Sight, Out of Mind? (Part 2)

This post follows an earlier post about DNS amplification attacks being observed around the world. DNS Amplification Attacks are occurring regularly and even though they aren't generating headlines targets have to deal with floods of traffic and ISP infrastructure is needlessly stressed -- load balancers fail, network links get saturated, and servers get overloaded. And far more intense attacks can be launched at any time. more

TeleGeography’s Interactive Submarine Cable Map Is a Fun and Fascinating View Into Infrastructure

Ever want to know where all the submarine cables are that provide part of the physical infrastructure of the Internet? Or which cities in the world have the most connectivity via submarine cables? (or which regions might be single points of failure?) In doing some research I stumbled across this excellent site from the folks at TeleGeography... It is a very well done and captivating (to me, anyway) view into where all the current and planned submarine cables are located. more

A Question of DNS Protocols

One of the most prominent denial of service attacks in recent months was one that occurred in March 2013 between Cloudflare and Spamhaus... How did the attackers generate such massive volumes of attack traffic? The answer lies in the Domain Name System (DNS). The attackers asked about domain names, and the DNS system answered. Something we all do all of the time of the Internet. So how can a conventional activity of translating a domain name into an IP address be turned into a massive attack? more

The Internet: Missing the Light

Today's Internet is wonderful for solving hard problems such as connecting to Amazon to buy goods or for using Netflix. Amazon and Netflix, among others, demonstrate what is possible if you put in enough effort. Yet if we are to understand the Internet we need to look beyond those applications to the simplest application such as sending one bit of information from a light switch to a light fixture. more

Name Collisions, Why Every Enterprise Should Care (Part 3 of 5)

Do you recall when you were a kid and you experienced for the first time an unnatural event where some other kid "stole" your name and their parents were now calling their child by your name, causing much confusion for all on the playground? And how this all made things even more complicated - or at least unnecessarily complex when you and that kid shared a classroom and teacher, or street, or coach and team, and just perhaps that kid even had the same surname as you, amplifying the issue! What you were experiencing was a naming collision (in meatspace). more

Provoking National Boundaries on the Internet? A chilling thought…

The impact of the recently revealed US government data collection practices may go well beyond the privacy ramifications outlined in the Internet Society's statement: expect a chilling effect on global, resilient network architecture. As governments of other countries realize how much of their citizens' traffic flows through the US, whether or not it is destined for any user or service there, expect to see moves to curtail connections to and through the US. more

Removing Need at RIPE

I recently attended RIPE 66 where Tore Anderson presented his suggested policy change 2013-03, "No Need -- Post-Depletion Reality Adjustment and Cleanup." In his presentation, Tore suggested that this policy proposal was primarily aimed at removing the requirement to complete the form(s) used to document need. There was a significant amount of discussion around bureaucracy, convenience, and "liking" (or not) the process of demonstrating need. Laziness has never been a compelling argument for me and this is no exception. more

Don’t Overlook the Network When Migrating to the Cloud

The success or failure of public cloud services can be measured by whether they deliver high levels of performance, security and reliability that are on par with, or better than, those available within enterprise-owned data centers... IDC forecasts that public cloud IT spending will increase from $40 billion in 2012 to $100 billion in 2016. To provide the performance, security and reliability needed, cloud providers are moving quickly to build a virtualized multi-data center service architecture, or a "data center without walls." more

Intelligence Exchange in a Free Market Economy

The U.S. Government is causing a huge disservice to protection and defense in the private sector (80%+ of CIKR) by creating an ECS that contains monetary incentive for a few large players to exert undue control over the availability, distribution, and cost of security threat indicators. While there may be a legitimate need for the federal government to share classified indicators to entities for protecting critical infrastructure, the over-classification of indicator data is a widely recognized issue that presents real problems for the private sector. ECS as currently construed creates monetary incentives for continued or even expanded over-classification. more

A Primer on IPv4, IPv6 and Transition

There is something badly broken in today's Internet. At first blush that may sound like a contradiction in terms. After all, the Internet is a modern day technical marvel. In just a couple of decades the Internet has not only transformed the global communications sector, but its reach has extended far further into our society, and it has fundamentally changed the way we do business, the nature of entertainment, the way we buy and sell, and even the structures of government and their engagement with citizens. In many ways the Internet has had a transformative effect on our society that is similar in scale and scope to that of the industrial revolution in the 19th century. How could it possibly be that this prodigious technology of the Internet is "badly broken?" more

Moving Beyond Telephone Numbers - The Need for a Secure, Ubiquitous Application-Layer Identifier

Do "smart" parking meters really need phone numbers? Does every "smart meter" installed by electric utilities need a telephone number? Does every new car with a built-in navigation system need a phone number? Does every Amazon Kindle (and similar e-readers) really need its own phone number? In the absence of an alternative identifier, the answer seems to be a resounding "yes" to all of the above. more

America Closing Down Its Copper Network - So What’s Next?

We have reported in the past on the rapid decline of the copper telecoms network in the USA. A decade ago BuddeComm predicted that it would be impossible to move two customer access networks in parallel towards the new fibre future, the one operated by the telcos and the other operated by the cable companies. At that stage we indicated that a possible outcome could be that the telcos would upgrade their networks to FttH and that the cable companies would become the key tenants on that network. more
