Discovery tool v3.1.9 return error when scanning IP address range

XMLWordPrintable

      Issue Summary

      Discovery tool v3.1.9 returns error when scanning a IP address range. For example, in the Scan Settings, if a single IP, or multiple IPs separated by the semi colon, then the scan is fine. But if the Scan Settings is configured with an IP range (192.168.0.0-20) or with a CIRD notation range, the scan will return error.

      This is reproducible on Data Center: (yes)

      Steps to Reproduce

      1. Install the Discovery tool version 3.1.9
      2. Configure the "Scan Settings" with an IP range

      Expected Results

      The expected result is that the scan would be performed correctly

      Actual Results

      The actual result is that the scan would fail and return the error below.

      The below exception is thrown in the discovery log:

      Workaround

      The work-around at the moment is to downgrade to previous version of the Discovery tool or not to use an IP range.
