Hilbert curves are a common method to visualize data related to IP address spaces. In this demo, we present Hilby, a React framework to create such visualizations both for IPv4 and IPv6. Hilby offers a new perspective on Hilbert curves by enabling interactive aggregation and deaggregation of prefixes of different lengths simultaneously. By combining this with other features, e.g., color, Hilby can display both fine details and coarse overviews of large amounts of multidimensional networking data in the same frame without sacrificing performance or user experience. We provide use cases where visualizations benefit from Hilbys capabilities in research and practice.
