LEARNING OBJECTIVE

Help and how to use ProtoLens

Find protocols and diagnostic tools

Use the sidebar search to filter the menu. Select a protocol to open its explorer, or select a diagnostic tool to open its lookup panel. The details panel explains the selected stage or tool.

Follow the connection journey

Use the previous and next controls to move through the journey. Watch the network diagram and read the event timeline to see what happens at each stage. Use Reset to return to the start.

Run a DNS lookup

Select a supported DNS lookup, enter a domain such as example.com, and choose Run lookup. Results show the records returned by public DNS. Tools that require server integration display an explanation in the results panel.

Change the color theme

Use the theme control in the header to switch between light and dark mode.
