21st Century Triple Networks: Ubiquitous 4G, WiFi, & Wires

The best engineers on the planet are coming to the same conclusion: a hybrid 4G/WiFi/landline network is the way to meet mobile demand. Folks like John Donovan of AT&T and Masayoshi Son of Softbank in Japan had this vision around 2007-2008. As the iPhone/iPad/Android made the coming demand clear, networks planners around the world evolved similar strategies. more

The End of the (IPv4) World is Nigher!

Funny how some topics seem sit on a quiet back burner for years, and then all of a sudden become matters of relatively intense attention. Over the past few weeks we've seen a number of pronouncements on the imminent exhaustion of the IP version 4 address pools. Not only have some of the Regional Internet Registries (RIRs) and some national registry bodies made public statements on the topic, we've now seen ICANN also make its pronouncement on this topic... Why the sudden uptake of interest in this topic? I suspect that a small part of this may be my fault! more

iPhone 6 VoLTE Will Disrupt the Mobile Industry

As far back as 2011 we predicted that Apple would eventually enter the voice market. We indicated at that time that it was just a matter of time -- in the end it took another three years... While it didn't happen at Christmas that year the company is now ready and will use the VoLTE service to enter this market, which will make it possible to replace Telstra with any other mobile operator around the world... he telcos are not ready for this. While they should be seen as the leaders in the voice call market they are too preoccupied with protecting their traditional business and it is companies like Apple and Samsung who are now leading the charge. more

Is IPv6 an Essential Precondition for Internet of Things? Or Are Things Just Fine with IPv4?

It has often been claimed that IPv6 and the Internet of Things are strongly aligned, to the extent that claims are made they are mutually reliant. An Internet of Things needs the massively expanded protocol address space that only IPv6 can provide, while IPv6 needs to identify a compelling use case to provide a substantive foundation to justify the additional expenditures associated with a widespread deployment of this new protocol that only the Internet of Things can provide. more

Video Dominates Internet Traffic As File Sharing Networks Overall Traffic Continues to Fall

Video continues to be the trend to watch as devices and tablets cater to higher definition content with larger screen sizes enabling the market for longer form video on mobile, reports Sandvine in its latest Internet traffic trends report. 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

Broadband Routers and Botnets: Being Proactive

In this post I'd like to discuss the threat widely circulated insecure broadband routers pose today. We have touched on it before. Today, yet another public report of a vulnerable DSL modem type was posted to bugtraq, this time about a potential WIRELESS flaw with broadband routers being insecure at Deutsche Telekom. I haven't verified this one myself but it refers to "Deutsche Telekom Speedport w700v broadband router"... more

IPv4 Address Exhaustion and a Trading Market

There are discussions starting within the Regional Internet Registries (RIRs) about the creation of trading market in IPv4 addresses as we approach the inevitable exhaustion of unallocated addresses. The view being put forward is basically "this is likely to happen anyway and by discussing it now, we can ensure it happens in an orderly way". When I first heard this idea I was a bit surprised. The RIRs are policy based bodies and so a shift to a trading market appears to be an abandonment of that policy base. However I have been partly corrected on that. more

AT&T’s Randall & Stankey: Wireless Data Growth Half The FCC Prediction

40%, not 92%-120%. "Data consumption right now is growing 40% a year," John Stankey of AT&T told investors and his CEO Randall Stephenson confirmed on the investor call. That's far less than the 92% predicted by Cisco's VNI model or the FCC's 120% to 2012 and 90% to 2013 figure in the "spectrum crunch" analysis. AT&T is easily a third of the U.S. mobile Internet and growing market share; there's no reason to think the result will be very different when we have data from others. more

Worm Propagation Strategies in an Ipv6 Internet

A recent paper called "Worm Propagation Strategies in an IPv6 Internet", written by Steven M. Bellovin, Angelos Keromytis, and Bill Cheswick, examines whether or not the deployment of IPv6 will in fact provide a substantial level of barrier against worms. Shared below are the introductory paragraphs from this paper. "In recent years, the internet has been plagued by a number of worms. One popular mechanism that worms use to detect vulnerable targets is random IP address-space probing..." more

Potential Impacts of Large-Scale Metaverses on Internet Governance: Bandwidth

Neal Stephenson’s foundational cyberpunk novel Snow Crash brought to the public the concept of a metaverse, a virtual reality in which people interact using avatars in a manufactured ecosystem, eschewing the limitations of human existence. More recently, Ready Player One capitalized on that idea and brought it back to prominence with a bestselling novel and subsequent film adaptation. Amid rebranding efforts and seeking a new way forward, Mark Zuckerberg has made it Facebook’s (now Meta Platforms) priority to build a platform that could enable the metaverse to become a mainstream technology with the sort of reach that their social networks and WhatsApp have. more

IP Address Management as a Service on the Cloud

Consumption of software as a service with a usage-based business model has gained incredible popularity in recent years. On the other hand, other cloud services such as infrastructure and platform as a service are just starting to pick up. While compute and storage are by the far the most commonly used cloud infrastructure services, few consider core network services such as IP Address Management (IPAM) as something that could be utilized over the cloud. more

Help Science Fight COVID-19

Many organizations and individuals are socially committed and voluntarily help the weak, the poor, and the sick. Others consider how they can contribute. Supporting organizations and individuals by starting an aid project, donating money, or providing human resources, can make a crucial difference. The corona crisis is a challenge for many, if not all. Scientists around the world are experimenting with cures and vaccines, and they need help. However, you don't have to be a virologist to help science fight COVID-19. more

How the End of IPv4 Affects Email and Hosting

Anyone who has been watching the technology industry for more than a couple of years quickly learns to recognize FUD: Fear, Uncertainty and Doubt. FUD is (apparently) widely believed to be an effective marketing technique, especially when it comes to security, privacy, or scarcity. But the FUD often falls flat. Scarcity, in particular, is rare on the internet -- even rarer than privacy or security. There's constant FUD about scarcity of bandwidth, but the pipes get upgraded. Attempts to impose artificial scarcity through paywalls or other devices inevitably fail in the face of free alternatives. Even the scarcity of IPv4 addresses, which have indeed run out at the top, hasn't affected end users at the bottom yet -- and probably won't, for a long time. more

Let’s Face Facts: We Need a New Industrial Internet

The Internet is a great success and an abject failure. We need a new and better one. Let me explain why. We are about to enter an era when online services are about to become embedded into pretty much every activity in life. We will become extremely dependent on the safe and secure functioning of the underlying infrastructure. Whole new industries are waiting to be born as intelligent machines, widespread robotics, and miniaturized sensors are everywhere. more
