Testing IXP Configurations Without Breaking Production: A Digital Twin Approach

Tommaso Caiazzi

• 23 Feb 2026

• 7 min read

Configuration mistakes at an IXP can have immediate impact. Building on the earlier IXP Digital Twin project, this article presents a new dashboard that enables operators to recreate production environments, validate routing state, and test member onboarding off production.

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

Maynard Koch

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…

Peering Market at a Glance: Trends, Transformations, and the Regional Dynamics of Internet Interconnection

DNSSEC and PQC: Practical Impact of Increased TCP in DNS

Eline Stehouwer

• 29 Jan 2026

• 17 min read

Post-quantum cryptography could make DNSSEC responses bigger, pushing more DNS traffic from UDP to TCP. In this guest post, Eline Stehouwer (SIDN Labs) explores what that means for authoritative name servers, replaying real .nl traffic across NSD, Knot, BIND and PowerDNS.

Raffaele Sommese - The Technical Impact of Rapid-Response Blocking: Italy’s Piracy Shield

• 2 min read

In our latest episode, Raffaele Sommese of the University of Twente shares insights from him and his colleagues on Italy’s Piracy Shield and how rapid-response blocking works in practice. We get into the technical impact, how it can be measured, and the consequences for connectivity.

Introducing Path Analysis: A New Way to Visualise Traceroute Changes in RIPE Atlas

Stephen Suess

• 17 Dec 2025

• 4 min read

RIPE Atlas now includes a new path analysis tool that makes it easier to understand how traceroute paths evolve over time. By comparing runs side by side, it highlights where the path changed and what kind of change it was. This gives you a fast, visual starting point for incident investigation, va…

A First Look at the Adoption of BGP-based DDoS Scrubbing Services

We present a first look at the adoption of BGP-based DDoS scrubbing, developing a methodology that sheds light on use of the global top five scrubbers. By identifying protected ASes and prefixes via four BGP AS-path patterns in RIS/RouteViews, we provide an initial overview of adoption across the I…

Unlocking Digital Growth: The Role of IXPs in South East Europe
