To add or update multiple scan ranges in bulk
If you have opted to configure custom scan ranges, it may be quicker to update them in bulk than to enter them one at a time. You can update them in bulk as follows:

  1. Scroll down to the Scan Range Bulk Update section of the page.
  2. In the Scan Ranges: field, enter in the scan ranges.
    • Enter one scan range per line
    • Use the following format: From_Address,To_Address,Subnet
  3. To add these ranges to the current list, click the Add ranges button.
  4. Or, to replace the current list entirely with these ranges, click the Replace ranges button.

For example, suppose you entered the following in the Scan Ranges field and then clicked the Add ranges button:
    192.168.0.0,192.168.0.255,255.255.255.0
    192.168.1.0,192.168.1.255,255.255.255.0

There would be two scan ranges added to the list: One scan range from 192.168.0.0 to 192.168.0.255 using the subnet 255.255.255.0, and a second range from 192.168.1.0 to 192,168.1.255 using the subnet 255.255.255.0.
