Since October 2014, we have been advertising two IPv4 /25s and two IPv4 /28s, to better understand how far they propagate across the network. In this article, we review how things have (or have not) changed over the years.

Uta Meier-Hahn is a doctoral researcher at the Humboldt Institute for Internet and Society in Berlin. In her work she focusses on informal regulation of internet infrastructure with specific interest in internet interconnection arrangements. As academic editor for the institute's Internet Policy Review (http://policyreview.info), Uta contributes to establishing a hybrid form of publication at the crossroads of journalism and academia. Before joining the institute, Uta worked as an online journalist for the public broadcasting company Norddeutscher Rundfunk. She studied Cultural Studies at the University of Lüneburg and at the Marmara University in Istanbul.
One of the most noble narratives about the Internet is that it is built on trust. This article sets out to check if that saying still holds true.
Last week, the Network Traffic, Measurement and Analysis Conference (TMA) took place in Maynooth, Ireland. A full week was scheduled, featuring a PhD school across Monday and Tuesday, the Mobile Network Measurements (MNM) workshop on Tuesday, and the main conference from Wednesday to Friday. We wer…
By analysing how resolvers select authoritative name servers in the wild we investigated how DNS operators are able to reduce DNS response times.

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.
Open DNS resolvers that answer queries coming from anyone have been the main component of a large number of DDoS attacks in recent years.
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 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 …

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.

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.
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.
