  • 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.
  • Tags
    —Expander provides the option of selecting tags from its database. Click on the search bar, and Expander displays a list of all tags. Select the tag and then click
