# Host

The host name or IP Address of the Content component that stores the category index (AgentStore). If you use stand-alone components in a distributed IDOL Server, use this parameter to specify the machine where the category index is located.

If you use a Distributed Action Handler (DAH) to distribute the category index between multiple instances of the AgentStore component, set `Host` to the host name or IP address of the DAH. In this case, you must also set IndexHost and IndexACIPort to the host and ACI port of the Distributed Index Handler (DIH) that distributes index actions to your category index.

NOTE: This parameter is meaningful only in a stand-alone Category component, not in a unified IDOL Server configuration.

IMPORTANT: If you set GSSServiceName, you must set `Host` to a fully qualified domain name (that is, for GSS authentication you cannot use `localhost`, an IP address, or a host without the domain name, even if these values resolve to the correct server).
