6. Select the Type as required.

  • To exclude individual IP addresses, choose IP Address List
  • To exclude multiple IP addresses as a group, select IP Address Range
  • For an IP Address Range, enter the starting IP address and the ending IP address

The next time discovery is run on the schedule, the IP addresses specified—either as individual addresses or in a range—should be excluded and not scanned.
