Every workflow run executes on machines with specific IP addresses. You can retrieve those addresses from two places: the Runs page and the Workflow Editor.
Navigate to the Runs page, open the action menu on any run, and select Export IP Addresses. A popup appears listing all IP addresses used during that run. From there you can copy the addresses to the clipboard or download them directly as a file.
Open the workflow in the editor and go to the Runs section. Open the action menu on the run and select Details. The run details panel displays the IP addresses used, which can be copied from there.
