Abstract Details

2017, Master of Sciences, Case Western Reserve University, EECS - Computer and Information Sciences.
Collaboration between a group of DNS service providers and Content Delivery Networks (CDNs) has led to an open IETF RFC — EDNS-Client-Subnet (ECS). ECS is an extension to the DNS protocol that helps its adopters to better direct client requests for content to a nearby server, thereby improving experiences for end users. In this thesis, we explore the state of adoption of ECS on the Internet: how many CDNs already support ECS and how widely ECS is adopted by the authoritative name servers and the resolvers. We also explore a security implication of ECS, in that it can simplify scanning of the entire set of servers used by a CDN. We show that Akamai, the largest CDN, has successfully addressed this potential vulnerability while other CDNs remain explored. Finally, by utilizing multiple vantage points, we are able to infer the extent to which individual CDNs collaborate with each other to form so-called federated CDNs, and discover that some content providers employ multiple CDNs to deliver their content.
