Beyond Origin Validation: Four Classes of Routing Attack Nobody Is Validating

Author image
Antonio Prado

8 min read

RPKI has made real progress against prefix hijacking. But when you map every known class of BGP attack against the defences that exist, four of them turn out to sit entirely outside cryptographic validation: handled with local filters, static thresholds and reactive response.

ASPA Is Live. Can You See It Working?

Author image
Ritesh Mukherjee

9 min read

ASPA objects can be registered today with ARIN and RIPE NCC. Validators support RTR v2. But if you're an operator, can you actually see what ASPA is doing - or would do - on your network? We built a tool to find out.

Legacy Out of Contract

Author image

19 min read

Last time, we looked at legacy address space in terms of contract coverage, ROA coverage, and proportion of announced prefixes. Now it’s time to take a closer look at those blocks still to be brought under contract and get a clearer picture of what kind of behaviour we see coming from them.

Using QUIC Backscatter to Infer Hypergiant Deployment Configurations

Author image
Jonas Mücke

10 min read

QUIC enhances privacy, but passive measurements still reveal deployment details. Using network telescope data, we analyse QUIC behaviour across major content providers and validate our findings with flow data and active measurements.

Towards Understanding City-Level Routing Using BGP Location Communities

Author image
Thomas Krenc

5 min read

BGP location communities offer a rare glimpse into where networks actually interconnect, but most remain undocumented and opaque. This work shows that, by exploiting a measurable spatial signal in routing data, it is possible to infer their city-level meaning at scale using only passive observation…

Introducing Region Meshes: Visualising Intra-Region Routing Paths

Author image
Stephen Suess

7 min read

Region Meshes is a new RIPE Atlas tool that visualises intra-region routing paths, showing where traffic stays local, where it leaves, and how IXPs are being used.

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.
