Adding a Sub-Group

Procedure

1. Go to Appliances → Network Assets → Network Groups.
   The Network Groups screen appears.
2. Click the menu icon beside a group name and then select Add sub-group.
   The Add New Sub-Group dialog appears and displays the parent group's IP address ranges.
3. Type a group name.

   Note Provide specific groups with descriptive names for easy identification of the network to which the IP address belongs. For example: "Finance network", "IT network", or "Administration".

4. Type an IP address or range.

   Note Added IP addresses must be inside the parent group’s IP address ranges. You can add up to 1,000 IP addresses or address ranges per group. The IP address or range cannot belong to Class D or Class E. The IP address or range cannot be a loopback address.

   1. Use a dash to specify an IP address range.
      The Network Groups window supports IPv4 and IPv6:
      • IPv4 example: 192.168.1.0-192.168.1.255
      • IPv6 example: 2620:1005::123-2620:1005::460
   2. Use a slash to specify the subnet mask/prefix for IP addresses.
      • IPv4 subnet mask example: 192.168.1.0/24
      • IPv6 subnet prefix example: fd00:1:1111:200::1000/116
5. Select whether to mark the IP address or address range as Trusted or Untrusted.
6. Click Add located next to the Monitored IP addresses field.
   The IP address or address range is added to the table below.
7. (Optional) Repeat steps 4 to 6 to add additional IP addresses or address ranges to this group.
8. Click Add.
   The item appears in the Network Groups list.
