Configure Cortex XDR network parameters

Define your internal IP address ranges and domain names to enable Cortex XDR to identify, track, and analyze network assets.

Define internal IP address ranges

The IP Address Ranges page displays the address ranges that Cortex XDR - Analytics monitors. Addresses are pre-populated with the default IPv4 and IPv6 address spaces. The names you define will appear when investigating the network-related events in Cortex XDR.

You can add a new IP address range manually or upload IP address ranges from a CSV file.
