ASmap dashboard: tracking the asmap-data history against the observed network

The process of enhancing the Top Movers table includes integrating individual prefix moves into edges, effectively summarizing shifts in IP ranges between networks as singular transitions from one network to another. For instance, multiple movements between Amazon's networks or from Penn State University to Vercara are each represented as direct edges. This approach simplifies the visualization of network traffic and emphasizes significant transitions.

A key feature proposed for improving the analysis of these data involves the introduction of a recurrence indicator. This metric would help identify how frequently each edge appears across historical release steps, thus distinguishing between routine internal reshuffles and unique, noteworthy events. For example, frequent repetitions of the same move within Amazon's networks suggest standard operational adjustments, whereas a rare shift from Penn State University to Vercara might indicate a significant change worth special attention.

To further refine the utility of the Top Movers table, a filter could be added to highlight only new or particularly large moves, leveraging both the size of the move and its novelty. This would focus attention on the most impactful or unusual changes in network configurations. However, capturing more nuanced details such as organizational shifts remains challenging due to limitations in the ASmap's knowledge of ASN affiliations. Addressing this would require integrating external ownership data, making it a best-effort heuristic rather than an exact measure.
