Overview

Satellite is a methodology, tool chain, and data-set for understanding global trends in website deployment and accessibility using a single or small number of standard end hosts. Satellite collects information on DNS resolution and resource availability around the Internet by monitoring the IPv4 address space. These measurements are valuable in their breadth and sustainability, since this machine collects a full data set on its own each week. Satellite is committed to openness, with all code and data made publicly available.

Satellite Dataset

  • Weekly DNS resolution of Alexa top 10,000 domains.
  • Reverse PTR, Server header, and relevant location data.

Writing

Satellite was presented at the 2016 USENIX Annual Technical Conference, and was awarded best student paper. The paper covers the design of the measurement system, and the ability for the bipartite graph of IPs and domains to reveal CDN infrastructure.
