Description

As a byproduct of our web-based Real User Monitoring (RUM) agent, Dyn obtains the IP addresses of individual hosts running web browsers all over the world as well as the IP addresses of the recursive servers queried by those hosts. We have analyzed a rich data set of over 110 million client IP address-to-recursive IP address mappings to research an area of DNS that we believe has not been sufficiently studied. For example, what is the distribution of the number of clients per recursive server? Where are clients located relative to the recursive servers they use, both from a geographic as well as network topological perspective? What query patterns do individual clients follow if they use multiple recursive servers? We report on these and other interesting findings.
