Is a Name Enough? A First Look into Detecting Clouds Using DNS Pointer Records
Year: 2024
Type: conference-paper
Abstract: The flexibility and scalability of cloud services have led to their adoption across various industries. While it is easy to identify deployments of very large cloud providers (hypergiants) as they often publish the allocation of their network resources, this is much less commonly the case for smaller providers. Despite efforts by commercial IP intelligence providers to bridge this gap, it is not clear how complete and reliable their data is, which is compounded by the lack of transparency surrounding their identification methods. In this early study, we utilize reverse DNS, a public data source provided and used by network operators, to identify the IP cloud space. We develop a Markov chain-based classifier to identify patterns and structures in the reverse DNS naming schemes of cloud providers. Our results indicate that cloud infrastructure naming often differs significantly from that of residential IP space, although there are some overlaps that require further investigation. We believe that our model can be used by network operators to identify cloud deployments with varying levels of confidence.
