Private IP ranges are used to isolate suspicious traffic data within controlled network segments.

You can manage the private IP Ranges using the Private IP Ranges tab in the General Security Settings user interface. These private IP ranges are applicable for use by the NSX Intelligence and the NSX Network Detection and Response features when you activate either feature.

If you activate the NSX Network Detection and Response feature, the system uploads the private IP ranges information to the NSX Network Detection and Response feature and some of the intrusion correlation rules use that information.

  • To enter an IPv4 IP range, click inside the IPv4 IP Range text box and enter the values, using the IPv4 IP CIDR notation format shown below the box. Press Enter for each entry, and click Save when finished.

  • To enter an IPv6 IP range, click inside the IPv6 IP Range text box and enter the values, using the IPv6 CIDR notation format shown below the box. Press Enter for each entry and click Save when finished.

The NSX Intelligence feature categorizes an IP address belonging to one of the CIDR notations listed in the dialog box as a private IP address. Any IP address that does not belong to any of these CIDR notations is classified as a public IP address. If the IP address of your VM or physical server does not fall into one of these CIDR notations, consider adding your CIDR notation using this Private IP Ranges UI.
