Hi all, My name is Nikolas Kühnlein and I am a computer science student at ETH Zürich, currently taking a course on computer networks. As part of my studies I have been exploring traceroute analysis and IP geolocation using latency triangulation — specifically trying to verify the physical location of intermediate hops using RTT measurements from distributed vantage points, rather than relying on WHOIS or commercial geolocation databases. I recently discovered RIPE IPmap and was impressed by how accurately it placed a Google border router in Zürich (contradicting a WHOIS record pointing to Mountain View, CA). I would like to run my own ping measurements from European probes to a small set of hop IPs from my traceroutes, to understand the triangulation method hands-on. As a new user I have no credits, and I am looking for a small donation to get started — a few million credits would be more than enough for what I have in mind. My RIPE Atlas account is registered under: nikshop@takuu.de I am happy to share my findings with the community. Thank you in advance for any help. Best regards, Nikolas Kühnlein ETH Zürich
