Consolidated Review of Mapping the Expansion of Google’s Serving Infrastructure

Another clever use of spoofing to gain insight into the infrastructure not otherwise practically feasible to obtain by researchers. The paper presents a nice and cute technique for mapping out a CDN provider's infrastructure. Although the techniques provided are specific to Google's CDN, the authors show how their technique can be used to quantify the coverage and accuracy of prior techniques. The presented techniques can also be used to enrich bittorrent client design, geolocation and other domains in networking.
