Arctic Wolf Unified Portal Telemetry Management

Add a host identification DNS server

To add DNS servers for hostname resolution, you can add a single IP address, IP address range, classless inter-domain routing (CIDR) range, or upload a CSV file that contains IP addresses.

  1. Sign in to the Arctic Wolf Unified Portal.

  2. Click Telemetry Management > Scanners.

  3. Click Configure for the scanner that you want to view.

    Tip: The scanner must be online for configuration changes. If needed, use filters to limit your results. See Scanner filters for more information.

  4. Click the Host DNS Servers tab.

  5. Do one of these actions:

    • Enter an IP address, IP address range, or a CIDR address range in the field.
    • Click Import, find your CSV file that contains the IP addresses, IP ranges, or CIDR notation that you want to use for hostname resolution, and then click Open.

    Notes:

    • To specify multiple IP addresses, use a - separator in one of the IP octets. For example, 10.0.0.1-3 expands to 10.0.0.1, 10.0.0.2, 10.0.0.3.
    • To specify a CIDR range, use a comma-separated list. You can enter individual hosts without the /32 specification or networks in the same CIDR X.X.X.X/Y.
    • When uploading a Microsoft Excel CSV file, do not use column headings. Only populate the first column. Separate entries by row.
    • Duplicate uploads are ignored. For example, if you create a CSV file with 10 entries and upload the CSV file to the Unified Portal, and then add 5 more entries to your CSV file and upload the same CSV file to the Unified Portal, only the 5 most recent entries are added as host identification DNS servers.
  6. Click Update Configuration.
