Procedure

1. Go to Administration → Network Groups and Assets → Network Groups.
2. Click Add.
   The Network Groups window appears.
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 range in the text box (up to 1,000 IP address ranges).

   Note The IP address range cannot contain a Class D or Class E address (224.0.0.0 - 255.255.255.255)

   Deep Discovery Inspector provides a default network group containing the following IP address blocks reserved by the Internet Assigned Numbers Authority (IANA) for private networks:

   • IPv4: 10.0.0.0 - 10.255.255.255
   • IPv4: 172.16.0.0 - 172.31.255.255
   • IPv4: 192.168.0.0 - 192.168.255.255
   • IPv6: fe80::-febf:ffff:ffff:ffff:ffff:ffff:ffff:ffff
   • IPv6: fc00::-fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff
   • IPv6: fec0::-feff:ffff:ffff:ffff:ffff:ffff:ffff:ffff

   Tip Create a new network group by editing the Default network group.

   1. Click Default to edit and add a new network group.
   2. 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
   3. 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

   Note Add up to three layers of sub-groups.

5. Select the Network zone.

   Note Trusted indicates a secure network and Untrusted indicates a degree of doubt about the security of the network.

6. Click Add.
7. Click Save.
