Use these steps to define hostnames and IP addresses (IPv4/IPv6). 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 CIDR notation (for example, 10.0.0.0/24).

  1. Click the Free-form IPs tab and do one of the following:
    1. If you are adding individual hostnames or IP addresses, type the each one on its own line.
    2. If you are defining 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. To discover these nodes, click Next.
  3. To specify other devices by IP address ranges or subnets, click IP Ranges or Subnets.
  4. To create a Do Not Scan list of devices within the ranges you have defined, click Do-Not-Scan List.
