Operating a DNS-based active internet observatory

Abstract

The Internet is subject to constant evolution. Its improvement requires understanding its current properties, a perspective provided by measurement studies. A key challenge in broadly studying evolution is to i) cover multiple protocols ii) with longitudinal measurements. In this poster, we present an Internet observatory that performs active measurements of multiple protocols (e.g., DNS, HTTP2, QUIC) regularly since 2016. Its measurements cover both i) the entire IPv4 address space and ii) > 50% of the domain name space to provide a new perspective on Internet evolution. The goal of this poster is to present its extensible architecture and capabilities, thereby aiming to foster collaboration.
