What is the IP address used as the Source IP in the OverFlow record type?

The IP address used as the Source IP in the OverFlow record type is 127.0.0.4. This is significant because the IP address 127.0.0.x typically represents the loopback interface on a device, which is used for testing and communication within the host itself. Specifically, 127.0.0.4 indicates a specific instance within the loopback range, which can be essential for internal applications and services to interact without needing to reach out to external networks.

In the context of QRadar and its handling of logs, using a loopback address as a source IP in OverFlow records allows the system to reference activities and incidents that occur locally, which can be critical for debugging and security monitoring. This distinction is important for understanding how events are logged and tracked within a SIEM environment.
