How reliable are the website popularity rankings like the Alexa top one million that many of us use in our research? We analysed four ranking lists and discovered the impact they have on research results and how easily they can be manipulated. For this reason, we created Tranco, a new improved p…

I am senior researcher at IIJ Research Lab. The focus of my work is on Internet measurements, traffic analysis and network security.
When withdrawing an IP prefix from the Internet, an origin network sends BGP withdraw messages, which are expected to propagate to all BGP routers that hold an entry for that IP prefix in their routing table. Yet network operators occasionally report issues where routers maintain routes to IP prefi…

Florian Streibelt is a PhD candidate at the Max Planck Institute for Informatics in Saarbrücken, Germany, supervised by Anja Feldmann. In 2013 he graduated with a Diploma Degree in computer science from Technische Universität Berlin. During his undergrad time at TU Berlin he worked as a systems administrator and as of today also as a freelancer. In 2013 he joined Anja Feldmann’s group back in Berlin based on the work he did on his diploma thesis “Exploring EDNS-client-subnet adopters in your free time” where he mapped the location of CDN caches to client networks and uncovered the caches located in ISP networks. His research interests include DNS, Internet measurement, protocol design, interdomain routing, security and data analytics. In his free time he enjoys amateur radio and electronics as in microcontroller programming.
This is the second of two articles in which we present a new attack vector on the routing infrastructure of the Internet using BGP communities.

Based in IMT Atlantique, Brest, France
I'm a PhD student at IMT Atlantique. My work concerns the optimization of active monitoring in computer networks through statistical modelling and prediction of the QoS.
Statistical characterisation of Round Trip Times (RTT) series is useful for network management. For example, if several paths are available between a source and a destination, say in a routing overlay context, it may be useful to select the path dynamically based on some inference on the current Qu…
Geoff Huston AM is the Chief Scientist at APNIC, where he undertakes research on topics associated with Internet infrastructure, IP technologies, and address distribution policies. From 1995 to 2005, Geoff was the Chief Internet Scientist at Telstra, where he provided a leading role in the construction and further development of Telstra's Internet service offerings, both in Australia and as part of Telstra's global operations. Prior to Telstra, Mr Huston worked at the Australian National University, where he led the initial construction of the Internet in Australia in the late 1980s as the Technical Manager of the Australian Academic and Research Network. He has authored a number of books dealing with IP technology, as well as numerous papers and columns. He was a member of the Internet Architecture Board from 1999 until 2005 and served as its Executive Director from 2001 to 2005. He is an active member of the Internet Engineering Task Force, where he currently chairs two Working Groups. He served on the Board of Trustees of the Internet Society from 1992 until 2001 and served a term as Chair of the Board in 1999. He has served on the Board of the Public Internet Registry and also on the Executive Council of APNIC. He chaired the Internet Engineering and Planning Group from 1992 until 2005.
Computers have always had clocks. Well maybe not clocks as you might think, but digital computers have always had oscillators, and if you hook the oscillator to a simple counter then you have a clock.
Based in Cambridge, MA, USA
I am a post doc researcher in the Advanced Network Architecture group at MIT and a research collaborator with Akamai Technologies. My current research centers around developing data-driven approaches to measure Internet reliability, resilience, and security. Prior to joining MIT, I earned my PhD (proof picture) from TU Berlin, advised by Anja Feldmann. In the summer of 2015, I was a research intern in the Custom Analytics Group at Akamai in Cambridge, Massachusetts. In the summers of 2013 and 2014, I was a visiting researcher at ICSI in Berkeley, California. I am broadly interested in methods to mine and understand data at scale with an emphasis on measurements assessing structure, performance, and security of the Internet. In my PhD work I explored the phenomenon of IPv4 address space exhaustion and its consequences for the Internet and its stakeholders. My research was awarded with a Best Paper Award at ACM IMC 2016, an IRTF Applied Networking Research Prize 2017, and selected “Best of CCR” in 2015.
Uninterrupted availability of the Internet has become increasingly critical these days, not just for end users but also for service providers who need to meet Service Level Agreements (SLAs). Yet, outages affecting end-user connectivity are widespread, whether they be unintentional fibre cuts, natu…

Welcome to the anticipated 2018 Quantum Internet Hackathon report. Here we share the results of last months’ successful hackathon held at the Volkshotel in Amsterdam.
On-path load balancing can send traffic across many potential paths, which typical traceroute usage will not fully capture. We are working on algorithms for a more complete traceroute across load-balanced paths, and we are interested in deployment on RIPE Atlas. We'd like your feedback.
