Research

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 understand the impact of often disregarded influences such as Off-Net deployments.

I am part of the Global Internet Observatory (GINO), an interest group at our chair focusing on Internet measurements. We maintain a variety of long-running measurement campaigns for DNS, QUIC, and we maintain the IPv6 Hitlist.

Besides these efforts, a colleague and I founded the 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. For more information about myself and latest news, also see johanneszirngibl.de.
