Abstract
This paper proposes Gollector, a novel tool for measuring the domain name space from different vantage points. Whereas such measurements have typically been conducted from a single (or few) vantage point, our proposed solution combines multiple measurements in a single system. Gollector allows us to express the relative difference in the covered domain name space, and the temporal characteristics, as domain name dark matter. We leverage a three-week trace from four vantage points, by applying the tool to three security-related use cases: early domain registration detection, data leakage in a split-horizon situation, and a proposed method for subdomain enumeration. We release the Gollector source code to the research community to support future research in this field.
