Host and network settings are under Configure > Networking: Host Settings.

When you initially run the Settings Wizard, you set required network host settings for the Core. You can configure or modify these settings:

Modify the hostname only if your deployment requires it.

We recommend that you use DNS resolution.

If you don’t use DNS resolution, or if the host does not have a DNS entry, you can add hosts to the system.

Configure proxy addresses for web or FTP proxy access to the Core.
