I am a research engineer in the R&D department at RIPE NCC. I am interested in internet measurements, internet outages, data analysis, and cybersecurity. Prior to joining RIPE NCC, I defended my Ph.D. in cyber-security at Delft University of Technology (TU Delft), The Netherlands.
Despite being a known vulnerability for at least 25 years, source IP address spoofing remains a popular attack method for redirection, amplification and anonymity. Preventing these attacks requires that operators implement Source Address Validation (SAV) to ensure their networks filter packets with…
In this article we use data from RIPE Atlas probes to investigate the usage of 240/4, a block of IPv4 addresses 'reserved for future use', formally known as Class E in the wild.

It was determined that middleboxes were to blame, intercepting the queries to the root instance hosted in China and sending a bogus reply.

“You do not mention the use of RIPE Atlas probes. Is the user tag "iwantbcp38compliancetesting" still useful/used?”
Thank you for taking the time to read my article and providing valuable feedback. Although I did consider discussing RIPE Atlas probes in my article, I ultimately chose to focus on the currently available methods for measuring BCP38. Regarding the "iwantbcp38compliancetesting" tag, while it was introduced in the past, it unfortunately never materialized. Nevertheless, if there is enough interest from the community, it could be worth exploring the possibility of implementing it in RIPE Atlas probes in the future. Once again, thank you for your comment and feel free to share any other insights or suggestions you may have.
