In a Security Information and Event Management (SIEM) integration, using a Fully Qualified Domain Name (FQDN) for specifying the SIEM server addresses can introduce potential security risks and complications such as DNS spoofing. Therefore, it is recommended to use IP addresses instead for more stable and secure communication. Using FQDN is generally not recommended unless there is a specific operational justification and proper security measures are in place.
