# Host

The IP address or host name of the machine that hosts the IDOL server.

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).

In non-mirror mode, you can also specify a comma-separated list of host names of mirrored child servers to create a child server group.

Type: | String
Default: |
Required: | Yes
Configuration Section: | IDOLServer`N` or DIHEngine`N`
Example: | `Host=10.1.1.10`
