Cortex Xpanse provides the ability to create a custom IP address range in the IP Ranges assets tab.

Cortex Xpanse provides the ability to create custom IP address ranges on the IP Ranges tab under Assets and on IP Range detail view pages.

To create a custom IP range, click on Create Custom Range on the IP Ranges list view or detail view page. The application opens a Custom Range Window with the following options for creating a custom IP address range:

  • Custom Ranges—On the IP Ranges List View, Expanse provides the capability to create a custom range based on IP Address, number of IPs, and tags:

    • First IP—Specify a valid IP/CIDR. Please note that unlike with IP/CIDR searches, you may not use wildcard characters.

    • Last IP—Specify a valid IP Address. If you entered a CIDR in the First IP, Cortex Xpanse automatically calculates the Last IP.

    • Number of IPs—Cortex Xpanse automatically calculates the number of IPs.

Once you click Create, Cortex Xpanse adds a new Custom Range listing to the IP Ranges List View.

To differentiate between standard ranges and custom ranges, Cortex Xpanse denotes parent and subset custom ranges with an icon to the left of the First IP Address.
