After you have defined subnets, IP address ranges, and other hostnames and IP addresses in which to discovery devices, exclude any devices (if any) from the ranges and subnets.

  1. Click the Do-Not-Scan List tab and do one of the following:
    1. If you are excluding individual hostnames or IP addresses, type the each one on its own line.
    2. If you are excluding a range within a subnet, type each range on its own line.
    3. In specifying a range of devices within a subnet, you can use format that delimits addresses with a hyphen (for example, 10.0.0.10-10.0.0.42 or 2001:db8:0:0:0:0:0:0-2001:db8:0:ffff:ffff:ffff:ffff:ffff) or CIDR notation (for example, 10.0.0.0/24 or 2001:db8::/48).

  2. When you are finished defining exclusions, click Next.
