IPv6 for Mobile Networks: Time to Act Now!

Mobile Network Operators (MNOs) serve the largest constituent of connected devices. There are over 4.6B GSM (and its derivatives) subscriptions today. When you add the CDMA family along with technologies with smaller footprints such as WiMax, IDEN to this list, that number tops 5B mark. On the other hand there are only (yes only!) 800M Internet hosts per ISC. Considering such a small percentage of those 5B or so devices are capable of being an Internet host and out of that percentage even a much smaller percentage is connected at a given time, one can understand the sheer potential of explosion in the number of Internet hosts as mobile devices in the next 3-5 years. more

AS Path Lengths Over Time - How Interconnected is the Internet?

One way to determine the denseness of the Internet, or its "interconnectedness", is to look at the path length between Autonomous Systems (ASes). The "shortest AS path" is a route selection rule in the Border Gateway Protocol (BGP) that means traffic from one AS will chose the path with the least number of ASes to get to the receiving AS. With IPv6 being deployed in parts of the Internet, we looked at the AS path length to see if the IPv6 portion of the Internet is more or less interconnected than the IPv4 Internet. more

United States Is the Most Bot-Infected Country. Right?

A couple of days ago, Threatpost posted an article indicating that the United States is the most bot-infected country... I think that Microsoft's mechanism of measuring bot infections is a good one, not necessarily because it is the most accurate but because it represents the most complete snapshot of botnet statistics. Because Microsoft Windows is installed on so many computers worldwide and because so many users across the world call home to the MSRT, Microsoft is able to collect a very large snapshot of data. more

IPv6 Momentum?

Last month, the Obama administration sponsored one of the first high-level government workshops on IPv6. At the meeting, the administration's Chief Information Officer, Vivek Kundra, announced a remarkable 2012 deadline for federal agencies to support IPv6. So with a high-level US government mandate and a recent spade of vendor and carrier IPv6 announcements (e.g. VeriSign, Hurricane Electric), is the 15 year old IPv6 migration effort finally gaining momentum? more

The Submarine Cable Conundrum

The boom and bust cycle of submarine cable deployment can be traced back to the 19th century. However it doesn't look as though we have learned a lot in those 150 years. One of the problems is that it generally takes two years to plan these international projects and two years to deploy the system. And even before the process commences there are often an initial two years when the potential builders are contemplating their plans. This means that new cables need to be planned at times when there is little demand for new capacity. more

Graph Shows Decline of IPv4 Has Been Mostly Linear

As the free pool of IPv4 addresses reaches its end, we looked at the evolution of the amount of unassigned IPv4 address space over time. By 'unassigned', we mean address space not yet allocated to a Local Internet Registry (LIR) or assigned to an end user. LIRs are typically Internet Service Providers or enterprises operating an IP network. See our findings in the graph below... more

Will US Government Directives Spur IPv6 Adoption?

Yesterday, the National Telecommunications and Information Administration of the U.S. government hosted a workshop discussing the state of IPv6 in the United States and its impact on industry, government, and the Internet economy. I was asked to be a panelist, along with industry executives from ARIN, ISOC, ICANN, Comcast, Akamai, Verizon, Google, VeriSign, DOE, NIST, and DREN. Moderated by Aneesh Chopra, Chief Technology Officer of the United States and Vivek Kundra, Chief Information Officer of the United States, this was the first event in the past few years to truly shine a spotlight on IPv6 adoption (or lack thereof) and introduce key directives to move this issue forward. more

IP Address Exhaustion In 12 Easy Questions

It seems that there is an increasing level of interest in the topic of IPv4 address exhaustion, so I thought I'll share a set of answers to the most common questions I've been asked on this topic in recent times. ... If there is a common factor in many of these challenges, it is scaling the network to meet an ever expanding agenda of more users, more devices, more traffic, more services and more policies. more

Network Complexity: Three Trends That are Contributing to a “Perfect Storm”

Most everyone who visits CircleID is familiar with Moore's Law, which stated simply holds that computing power doubles every 18 months. This has been going on since the 1960s and shows no sign of slowing. Moore's Law drives faster and faster computing, which produces more and more data and network complexity. This inexorable trend is putting immense pressure on corporate networks, and the strain is too much for many of them to handle on their own. more

Policy Failure Enables Mass Malware: Part I (Rx-Partners/VIPMEDS)

This is the first in a series of releases that tie extensive code injection campaigns directly to policy failures within the Internet architecture. In this report we detail a PHP injection found on dozens of university and non-profit websites which redirected visitor's browsers to illicit pharmacies controlled by the VIPMEDS/Rx-Partners affiliate network. This is not a unique problem, however the pharmacy shop sites in question: HEALTHCUBE[DOT]US and GETPILLS[DOT]US should not even exist under the .US Nexus Policy. more
