Noisy Routers: Investigating the Make-Up of Route Collector Data

Author image
Ebrima Jaw

11 min read

Analysis of 80B+ BGP updates shows repeated "noise" is highly concentrated in a small set of peers, sessions, and prefixes, inflating datasets. Researchers from Twente, CAIDA, SIDN Labs, and IIJ examine impacts on measurement and operations.

Beyond the Network View: DNS-Driven Application Visibility

Author image
Danny Lachos

6 min read

Network operators often lack visibility into which applications drive their traffic. We present an open-source DNS-based correlation method that enriches NetFlow and BGP data with application and CDN information. This enables a shift from a network-centric to an application-oriented view of traffic.

Forward to Hell? On Misusing Transparent DNS Forwarders For Amplification Attacks

Author image
Maynard Koch

10 min read

DNS infrastructure is infamous for facilitating reflective amplification attacks. Countermeasures such as server shielding, access control, rate limiting and protocol restrictions have improved the situation, but DNS-based reflective amplification attacks persist. Focusing on the threat vector intr…
