Hi all, My name is Sarah Zhao and I am a Computer Science and Engineering student at UCLA. I am currently conducting undergraduate research in computer networking at the UCLA Connection Lab under the mentorship of Professor Leonard Kleinrock. As part of my research I am studying the deployment and impact of Carrier-Grade NAT (CGN) at Internet scale. I plan to use RIPE Atlas traceroute measurements to detect CGN presence via 100.64.0.0/10 address leakage in hop paths, and TCP connect measurements to probe inbound reachability from CGN and non-CGN ASes as comparative vantage points. I need geographically diverse probes across networks in developing regions where CGN deployment is most concentrated. As a new user I have no credits and kindly ask for a donation to get started. An allocation of 200,000 credits would cover my planned measurement phases. My RIPE Atlas account is registered under: sarahzhao01@gmail.com I am very eager to share my findings with the community. Thank you in advance for any help! Best, Sarah Zhao UCLA Computer Science
