On 30 September 2026, Bucharest hosted a new edition of Internet Measurement Day, bringing together members of the technical and Internet community for a full day dedicated to understanding how the Internet works, how it can be measured and how measurement data can contribute to a more resilient and secure Internet.






The event took place at the Radisson Blu Hotel Bucharest and was organised by RIPE NCC and ICANN, with InterLAN as host and Internet Society as Institutional Partner.
Internet Measurement Day is part of a series of events organised across the RIPE NCC service region, aimed at bringing Internet measurement tools, data and expertise closer to local technical communities. The programme provided participants with an opportunity to explore practical applications of Internet measurement, exchange experience and discuss some of the challenges currently facing networks and Internet infrastructure.
The day opened with remarks from Eric Andrei Băleanu, President of InterLAN, together with representatives of RIPE NCC and ICANN, setting the scene for a programme focused on practical Internet measurement and the value of open data for the technical community.
The first technical sessions examined the way routing information can be used to better understand the Internet.
Alex Semenyaka of RIPE NCC presented an analysis of BGP paths using data from the Routing Information Service, RIS, looking at outdated technologies and anomalies that can be identified through routing information.
This was followed by Ulrich Wisser of ICANN, who introduced KINDNS, an initiative designed to encourage the adoption of DNS operational best practices.
Augustin Formoso of RIPE NCC then explored how operators can analyse routing using RIPEstat and RIS, demonstrating how publicly available measurement data can provide a clearer view of network behaviour and routing activity.
The afternoon programme continued with a strong focus on DNS, Internet infrastructure and locally relevant measurement data.
Ulrich Wisser presented ICANN Domain Metrica and ICANN’s research into security, stability and resiliency, before looking specifically at L-root traffic in Romania.
The agenda also brought local research into the discussion. Radu Anghel of TU Delft presented Aliens Among Us: Observing Bogon IPs on the Public Internet, examining traffic involving IP address space that should not normally appear on the public Internet.
Alexandra Ilie of the National University of Science and Technology POLITEHNICA Bucharest addressed another important local topic in Romania’s fibre is ready. Are we using it?, bringing the discussion closer to Romania’s own connectivity landscape and the way available infrastructure is being used.
Together, the sessions demonstrated how measurement data can help operators and researchers move beyond assumptions and gain a clearer, evidence-based view of what is actually happening across networks.
Internet Measurement Day Bucharest was not limited to technical presentations.
The final part of the programme focused on opportunities for greater engagement between academia, industry and the wider Internet community. Representatives of RIPE NCC, ICANN and Internet Society presented programmes and initiatives available to professionals, students, researchers and members of the technical community, including fellowships, training, certification and community participation opportunities.
Participants also had the opportunity to take RIPE NCC Academy certification exams during the event, covering areas including BGP Security, IPv6, the RIPE Database and LIR Fundamentals.
For InterLAN, hosting Internet Measurement Day in Bucharest represented another opportunity to support the development of Romania’s Internet community and encourage the exchange of technical knowledge between local and international experts.
Reliable Internet infrastructure depends not only on capacity and connectivity, but also on the ability to understand how networks behave. Open measurement platforms, shared data and collaboration between operators, researchers and technical organisations all play an important role in building a more resilient Internet.
We would like to thank RIPE NCC, ICANN and Internet Society, all speakers, participants and members of the community who contributed to Internet Measurement Day Bucharest 2026.
Through events such as IMD, technical knowledge becomes easier to share, measurement tools become more accessible, and the Internet community gains new opportunities to learn from one another.
