Internet-Security.com TCP port 5006 details

Bokeh Server (Python data visualization framework) listens on TCP port 5006 by default when you run bokeh serve for interactive apps and dashboards.
HoloViz Panel (built atop Bokeh) also defaults to TCP 5006 when launched with panel serve, powering Panel/hvPlot/Datashader dashboards.
Many Anaconda-distributed examples and tools that start Bokeh-based apps (e.g., via bokeh serve in Jupyter/conda environments) bind to 5006 unless a different --port is specified.
