Why is the Internet so Slow?
I wrote the articles collected here during my time as community builder of the RIPE NCC and the maintainer and editor of RIPE Labs. I have since taken on a new role serving as the Chair of the RIPE Community. You can reach my new profile via the website link below.
Ilker Nadi Bozkurt and his colleagues found that the Internet is much slower than it could be. They wonder where this slowdown comes from and what can be done about it.
Finding Open DNS Resolvers on IPv6
Luuk is a PhD candidate at the University of Twente, the Netherlands. His interests revolve around IPv6-specific measurements with a focus on security. And corgis.
Open DNS resolvers that answer queries coming from anyone have been the main component of a large number of DDoS attacks in recent years.
Introduction to the Quantum Internet
Vesna Manojlovic is Community Builder at RIPE NCC. Vesna joined the RIPE NCC as a Trainer in 1999. In 2003, she took responsibility for developing and delivering advanced courses, such as RPSL, Routing Registry, DNSSEC and IPv6. In 2008, she lead efforts to establish IPv6 RIPEness as a measure of IPv6 deployment among LIRs. In 2011, she joined the Science Division as Manager of the Measurements Community Building team; in 2015 she moved to Communications Department as Senior Community Builder, with a focus on organising hackathons. Vesna gives presentations at many technical conferences and workshops, and enjoys visiting hackerspaces. Vesna received a Batchelor of Sciences Degree in Computer Science and Informatics from the School of Electrical Engineering, University of Belgrade. She has three children.

BGP Table Fragmentation: What & Who?
I am a graduate student at the university of Strasbourg in France, currently working on iBGP correctness.
BGP routing table growth is one of the major Internet scaling issues, and prefix deaggregation is thought to be a major contributor to table growth. In this work we quantify the fragmentation of the routing table by the type of IP prefix. We observe that the proportion of deaggregated prefixes has …
RIPE NCC Technical Services 2017 - Part Three: Focus on Tools and Research
As Chief Information Officer at the RIPE NCC, I am mainly involved with the planning, operation and development of the RIPE NCC's global information services as well as research and development. This includes the RIPE NCC's authoritative DNS services as well as K-root infrastructure, data collection and measurement networks such as RIPE Atlas and RIS, data provisioning systems such as RIPEstat, and the RIPE NCC's data analysis efforts. I have been with the RIPE NCC since 2008 working in different capacities. Before the RIPE NCC, I worked for more than 12 years in the Internet services and ISP sectors, mostly in senior technical management positions. I was the engineering founder of one of the largest Iranian ISPs and helped several IT startups with their software and business process implementations. I have a M.Sc. in Software Engineering from the University of Oxford, UK and Lean Engineering/Agile Management training at MIT.
Please find below the third part of our technical services update. This time we're focusing on our research activities and a number of tools we are developing.
BBR TCP
Geoff Huston 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 for 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.
The Internet was built using an architectural principle of a simple network and agile edges. The basic approach was to assume that the network is a simple collection of buffered switches and circuits. As packets traverse the network they are effectively passed from switch to switch.
IETF 98 - Some Impressions - Monday
I wrote the articles collected here during my time as community builder of the RIPE NCC and the maintainer and editor of RIPE Labs. I have since taken on a new role serving as the Chair of the RIPE Community. You can reach my new profile via the website link below.
Here is a short summary of my Monday at IETF 98 in Chicago. Highlights were DNS operations and an effort to standardise address management systems.
Time to Decide on Internet of Things Liability
Eireann is interested in the intersections of security, privacy, hacking, data science, AI, network cartography, and economics.
We are at a very important decision point in Internet history. Will we accept insecure and unsafe Internet of Things (IoT) devices that erode our privacy and open our home networks to intrusion from hackers? Or will we hold vendors accountable for their security and privacy decisions in the product…
Reasons Dynamic Addresses Change
I am a sixth year PhD student and I love measuring networks: their topology, connectivity and performance. Growing up in places with poor Internet connectivity, I have a strong interest in measuring connectivity problems, such as loss and high latency, especially in the context of residential networks where their effect on end-users can be high. My current research focusses upon measuring residential Internet connectivity using active probes: how to detect outages using active probes and how to account for errors introduced by the use of active probes. I am also studying the topology of the Internet and eventually plan to correlate outages with topological changes when possible.
We look into why dynamic addresses change and find ISPs that renumber periodically, most commonly every 24 hours or a multiple of 24 hours. We also find that outages influence address changes.
Ethics of RIPE Atlas Measurements
I am the leader of the Research and Development team at the RIPE NCC leading a dedicated team of thinkers to support the RIPE community by providing network research, data analysis and prototype tool development and services including RIPE Atlas and RIPEstat.
This article is intended to make RIPE Atlas users aware of ethical issues that could arise when using RIPE Atlas. We do not intend to propose any new formal processes or procedures to address the relevant ethical issues, but we do want to encourage members of the RIPE Atlas community to consider th…
