Which options are available for the connection_host attribute in inputs.conf?

The connection_host attribute in inputs.conf is utilized to define how Splunk categorizes the source of incoming data. When configuring this attribute, the options available include DNS, IP, and none.

Choosing DNS allows Splunk to use the DNS name of the host that is sending data, which can be beneficial for maintaining a more human-readable representation of log sources. The IP option enables the system to report the sending host's IP address, which is often used for identifying network devices or when hosts do not have resolvable DNS names. Finally, selecting none indicates that no specific hostname or IP address will be associated with the incoming data, which may be suitable in scenarios where the source is not relevant or needed for context.

The other options listed do not correctly include the complete set of available configurations for the connection_host attribute. Understanding these attributes is key for effective data categorization and management in Splunk, making it easier to filter and search data based on the source.
