How to use the Ignore List

This guide shows you how to add devices to a segment's Ignore List so that they are excluded from subsequent scans and audits, and how to restore them later.

Prerequisites

  • Site Administrator role (moving devices to the Ignore List is Administrator-only).
  • A segment that has scanned at least once and has discovered devices in Scan Results.

Steps

Move discovered devices to the Ignore List

  1. Navigate to Network > Segments and click the segment name to open its detail view.
  2. In the Scan Results grid, tick the checkboxes next to the devices you want to exclude.
  3. Click Move to Ignore list in the toolbar.

  4. AlloyScan asks which identifier attribute to use for the Ignore List entry:

    • NetBIOS: Stable Windows NetBIOS name.
    • DNS: Stable DNS hostname.
    • MAC address: Stable hardware identifier -- best for printers and switches.
    • IP address: Use only if the IP is reserved or static; warned as potentially non-stable.

  5. Confirm the choice. AlloyScan removes the rows from Scan Results and adds the chosen identifier to the segment's Ignore List.

Edit the Ignore List directly

  1. Open the segment's Ignore List from the Segment Open view.
  2. Add or remove identifiers, one per line. Lines that start with # are treated as comments.

Verify

After confirming, the Ignored nodes counter on the Last scan statistics panel increments, and the device no longer appears in Scan Results. Run a fresh scan to confirm the device is also absent from the new results.

To restore a device, edit the segment's Ignore List and remove the identifier line. The device reappears on the next scan.
