Scanning the IPv6 Internet Using Subnet-Router Anycast Probing
Maynard Koch, Raphael Hiesgen, Marcin Nawrocki +2
Identifying active IPv6 addresses is challenging. Various methods emerged to master the measurement challenge in this huge address space, including hitlists, new probing techniques…
Waiting for QUIC: Passive Measurements to Understand QUIC Deployments
Jonas Mücke, Marcin Nawrocki, Raphael Hiesgen +6
QUIC experiences a rapid adoption since its standardization in 2021, and hypergiants configure their infrastructure to optimize for QUIC performance. In this paper, we introduce a…
A Detailed Measurement View on IPv6 Scanners and Their Adaption to BGP Signals
Isabell Egloff, Raphael Hiesgen, Maynard Koch +2
Scanners are daily visitors of public IPv4 hosts. Scanning IPv6 nodes successfully is still a challenge, which an increasing crowd of actors tries to master. In this paper, we anal…
A Call to Reconsider Certification Authority Authorization (CAA)
Pouyan Fotouhi Tehrani, Raphael Hiesgen, Thomas C. Schmidt +1
Certification Authority Authentication (CAA) is a safeguard against illegitimate certificate issuance. We show how shortcomings in CAA concepts and operational aspects undermine it…
ReACKed QUICer: Measuring the Performance of Instant Acknowledgments in QUIC Handshakes
Jonas Mücke, Marcin Nawrocki, Raphael Hiesgen +2
In this paper, we present a detailed performance analysis of QUIC instant ACK, a standard-compliant approach to reduce waiting times during the QUIC connection setup in common CDN…
The Age of DDoScovery: An Empirical Comparison of Industry and Academic DDoS Assessments
Raphael Hiesgen, Marcin Nawrocki, Marinho Barcellos +14
Motivated by the impressive but diffuse scope of DDoS research and reporting, we undertake a multistakeholder (joint industry-academic) analysis to seek convergence across the best…
