Welcome
As a researcher at the Max Planck Institue for Informatics, I focus on large scale analysis and measurements targeting the Internet. My core areas are the analysis of network deployments and their peculiarities. My work relies on multiple protocols spanning networking layers, such as IPv6, DNS, TLS, QUIC. The goal is to reach a better understanding of the Internet and the impact of often disregarded influences such as Off-Net deployments.
Previously, I did my PhD at the Chair of Network Architecures and Services at the Technical University of Munich.
I am co-leading the Global Internet Observatory (GINO), an interest focusing on Internet measurements. Over the years, we acquired vast knowledge in the area of large scale network measurements. This helps us to understand the current network state and its development. We seek to be harmless and conduct all measurements in an ethical manner.
Recent News
Max Planck Institue for Informatics
After five successful years as PhD student at the Technical University of Munich, I started a new position at the Internet Architectures group at the Max Planck Institute for Informatics.
IPv6 Hitlist Extension
Two weeks Lion Steger presented our latest insights and extensions to the IPv6 Hitlist Service at TMA 2023 and received the best paper award. The work categorized the Hitlist based on network types and evaluated target generation algorithms under different conditions. The paper is avaialable for more information. We further added a new historic and ongoing categorization as part of the Hitlist service for everybody to use. New responsive addresses will also be visible shortly.
QUIC Interest Group and IFIP 2023
Together with a colleague, I founded a QUIC Interest Group that brings together researchers and students with an interest in QUIC. Interests cover performance measurements, the analysis of different libraries but also Internet-wide measurements to evaluate QUIC deployments.
An outcome of this group, a performance evaluation of different libraries on a 10G link has been accepted to be published at IFIP Networking 2023. You can find a preprint of this work here
PAM 2023
One of our papers has been accepted to the PAM 2023.
