WHEREIS: IP Address Registration Geo-Consistency
Robert Beverly, Amreesh Phokeer, Oliver Gasser
The five Regional Internet Registries (RIRs) provide the critical function of IP address resource delegation and registration. The accuracy of registration data directly impacts In…
Packed to the Brim: Investigating the Impact of Highly Responsive Prefixes on Internet-wide Measurement Campaigns
Patrick Sattler, Johannes Zirngibl, Mattijs Jonker +3
Internet-wide scans are an important tool to evaluate the deployment of services. To enable large-scale application layer scans, a fast, stateless port scan (e.g., using ZMap) is o…
Analyzing IoT Hosts in the IPv6 Internet
Peter Jose, Said Jawad Saidi, Oliver Gasser
Users and businesses are increasingly deploying Internet of Things (IoT) devices at home, at work, and in factories. At the same time, we see an increase in the use of IPv6 for Int…
Live Long and Prosper:Analyzing Long-Lived MOAS Prefixes in BGP
Khwaja Zubair Sediqi, Anja Feldmann, Oliver Gasser
BGP exchanges reachability information in the form of prefixes, which are usually originated by a single Autonomous System (AS). If multiple ASes originate the same prefix, this is…
Target Acquired? Evaluating Target Generation Algorithms for IPv6
Lion Steger, Liming Kuang, Johannes Zirngibl +2
Internet measurements are a crucial foundation of IPv6-related research. Due to the infeasibility of full address space scans for IPv6 however, those measurements rely on collectio…
How Ready Is DNS for an IPv6-Only World?
Florian Streibelt, Patrick Sattler, Franziska Lichtblau +4
DNS is one of the core building blocks of the Internet. In this paper, we investigate DNS resolution in a strict IPv6-only scenario and find that a substantial fraction of zones ca…
Characterizing the VPN Ecosystem in the Wild
Aniss Maghsoudlou, Lukas Vermeulen, Ingmar Poese +1
With the shift to working remotely after the COVID-19 pandemic, the use of Virtual Private Networks (VPNs) around the world has nearly doubled. Therefore, measuring the traffic and…
Exploring the Cookieverse: A Multi-Perspective Analysis of Web Cookies
Ali Rasaii, Shivani Singh, Devashish Gosain +1
Web cookies have been the subject of many research studies over the last few years. However, most existing research does not consider multiple crucial perspectives that can influen…
FlowDNS: Correlating Netflow and DNS Streams at Scale
Aniss Maghsoudlou, Oliver Gasser, Ingmar Poese +1
Knowing customer's interests, e.g. which Video-On-Demand (VoD) or Social Network services they are using, helps telecommunication companies with better network planning to enhance…
Illuminating Large-Scale IPv6 Scanning in the Internet
Philipp Richter, Oliver Gasser, Arthur Berger
While scans of the IPv4 space are ubiquitous, today little is known about scanning activity in the IPv6 Internet. In this work, we present a longitudinal and detailed empirical stu…
Kirin: Hitting the Internet with Millions of Distributed IPv6 Announcements
Lars Prehn, Pawel Foremski, Oliver Gasser
The Internet is a critical resource in the day-to-day life of billions of users. To support the growing number of users and their increasing demands, operators have to continuously…
Deep Dive into the IoT Backend Ecosystem
Said Jawad Saidi, Srdjan Matic, Oliver Gasser +2
Internet of Things (IoT) devices are becoming increasingly ubiquitous, e.g., at home, in enterprise environments, and in production lines. To support the advanced functionalities o…
Rusty Clusters? Dusting an IPv6 Research Foundation
Johannes Zirngibl, Lion Steger, Patrick Sattler +2
The long-running IPv6 Hitlist service is an important foundation for IPv6 measurement studies. It helps to overcome infeasible, complete address space scans by collecting valuable,…
Hyper-Specific Prefixes: Gotta Enjoy the Little Things in Interdomain Routing
Khwaja Zubair Sediqi, Lars Prehn, Oliver Gasser
Autonomous Systems (ASes) exchange reachability information between each other using BGP -- the de-facto standard inter-AS routing protocol. While IPv4 (IPv6) routes more specific…
A Longitudinal View at the Adoption of Multipath TCP
Tanya Shreedhar, Danesh Zeynali, Oliver Gasser +2
Multipath TCP (MPTCP) extends traditional TCP to enable simultaneous use of multiple connection endpoints at the source and destination. MPTCP has been under active development sin…
SRv6: Is There Anybody Out There?
Victor-Alexandru Pădurean, Oliver Gasser, Randy Bush +1
Segment routing is a modern form of source-based routing, i.e., a routing technique where all or part of the routing decision is predetermined by the source or a hop on the path. S…
One Bad Apple Can Spoil Your IPv6 Privacy
Said Jawad Saidi, Oliver Gasser, Georgios Smaragdakis
IPv6 is being more and more adopted, in part to facilitate the millions of smart devices that have already been installed at home. Unfortunately, we find that the privacy of a subs…
Third Time's Not a Charm: Exploiting SNMPv3 for Router Fingerprinting
Taha Albakour, Oliver Gasser, Robert Beverly +1
In this paper, we show that adoption of the SNMPv3 network management protocol standard offers a unique -- but likely unintended -- opportunity for remotely fingerprinting network…
From Single Lane to Highways: Analyzing the Adoption of Multipath TCP in the Internet
Florian Aschenbrenner, Tanya Shreedhar, Oliver Gasser +2
Multipath TCP (MPTCP) extends traditional TCP to enable simultaneous use of multiple connection endpoints at the source and destination. MPTCP has been under active development sin…
Zeroing in on Port 0 Traffic in the Wild
Aniss Maghsoudlou, Oliver Gasser, Anja Feldmann
Internet services leverage transport protocol port numbers to specify the source and destination application layer protocols. While using port 0 is not allowed in most transport pr…
The Lockdown Effect: Implications of the COVID-19 Pandemic on Internet Traffic
Anja Feldmann, Oliver Gasser, Franziska Lichtblau +9
Due to the COVID-19 pandemic, many governments imposed lock downs that forced hundreds of millions of citizens to stay at home. The implementation of confinement measures increased…
Reserved: Dissecting Internet Traffic on Port 0
Aniss Maghsoudlou, Oliver Gasser, Anja Feldmann
Transport protocols use port numbers to allow connection multiplexing on Internet hosts. TCP as well as UDP, the two most widely used transport protocols, have limitations on what…
