China Telecom Accused of Misdirecting Internet Traffic

A paper published by the Naval War College titled, "China's Maxim - Leave No Access Point Unexploited: The Hidden Story of China Telecom's BGP Hijacking," accuses the Chinese government of manipulating BGP routing in order to intercept internet traffic. more

Ossification and Fragmentation: The Once and Future ‘net

Mostafa Ammar, out of Georgia Tech recently posted an interesting paper titled The Service-Infrastructure Cycle, Ossification, and the Fragmentation of the Internet. I have argued elsewhere that we are seeing the fragmentation of the global Internet into multiple smaller pieces, primarily based on the centralization of content hosting combined with the rational economic decisions of the large-scale hosting services. The paper in hand takes a slightly different path to reach the same conclusion. more

US Senators Urge Canada to Drop China’s Huawei Technologies in Building Future Telecom Networks

Google Signs Memoranda of Understanding With Four Cuban Organizations

Cuban President Miguel Díaz-Canel addressed the first annual meeting of Cuba's IT professional society, the Unión de Informáticos de Cuba. In his talk, Díaz-Canel announced that four Cuban organizations - the Havana City Historian's Office, the University of Computer Sciences (UCI), Infomed, Cuba's medical network, and the Ministry of Culture had signed memoranda of understanding (MOUs) with Google. more

IPv6 Security Considerations

When rolling out a new protocol such as IPv6, it is useful to consider the changes to security posture, particularly the network's attack surface. While protocol security discussions are widely available, there is often not "one place" where you can go to get information about potential attacks, references to research about those attacks, potential counters, and operational challenges. more

Internet Society Partnering With Facebook to Develop Internet Exchange Points Throughout Africa

The Internet Society today announced that it is partnering with Facebook to develop Internet Exchange Points (IXP) throughout Africa. more

BGP Security: A Gentle Reminder that Networking is Business

At NANOG on the Road (NotR) in September of 2018, I participated in a panel on BGP security -- specifically the deployment of Route Origin Authentication (ROA), with some hints and overtones of path validation by carrying signatures in BGP updates (BGPsec). This is an area I have been working in for... 20 years? ... at this point, so I have seen the argument develop across these years many times, and in many ways. more

Microsoft Cancels Plans to Move Its Internal Wireless Network to IPv6-Only

Microsoft has digressed from a previously announced plan to move its internal wireless guest network to IPv6-only. more

Getting on with Digital Transformation: Three Steps to Making Strategic Technology Choices

In a recently published Uptime Institute Survey, Uptime Institute found that organizations operating data centers are finding it increasingly difficult to recruit professionals skilled in security, networking, and hybrid technologies. This realization comes at an interesting time, as the monolithic business infrastructure built over the last two decades is now entering a period of transformation. more

Large-Scale Study by Security Researchers in China Sheds Light on the Scope of DNS Interception

During the 27th Usenix Security Symposium held in Baltimore, MD last week, a group of researchers from China revealed results obtained from a large-scale analysis DNS interceptions. more

Join the Quantum Internet Hackathon 2018

The eighth RIPE NCC hackathon takes on the Quantum Internet! The hackathon will be held during the weekend before RIPE 77 in Amsterdam, and is co-organised by QuTech and TU Delft, along with the RIPE NCC. We're bringing together network operators, quantum networking researchers, students, hackers, software developers and artists, to imagine and build the tools for the future Internet. more

Nerd Knobs and Open Source in Network Software

Tech is commoditizing. I've talked about this before; I think networking is commoditizing at the device level, and the days of appliance-based networking are behind us. But are networks themselves a commodity? Not any more than any other system. We are running out of useful features, so vendors are losing feature differentiation. This one is going to take a little longer... more

Group of Engineers Have Created a Way to Detect Dangerous Objects in Baggage Using Public Wifi

Report describes a technique with which public wifi can be used to identify in-baggage dangerous objects in public spaces that don't typically have affordable screening options. more

Escalating War in Yemen Dividing Country’s Internet

"The latest development in Yemen's long-running civil war is playing out in the global routing table," Doug Madory reports in a blog post today from Oracle's Internet Intelligence unit. more

An Update on Securing BGP from IETF 102

One way or another we've been working on various aspects of securing the Internet's inter-domain routing system for many years. I recall presentations dating back to the late '90's that point vaguely to using some form of a digital signature on BGP updates that would allow a BGP speaker to assure themselves as to the veracity of a route advertisement. more
