                    CAST Extend local server/Offline is only required if (due to security concerns for example) your organization/AIP Console cannot interact over the public internet with CAST's Extend system for Extension management. CAST currently offers two separate but similar "offline" packages that can be installed:
| CAST Extend local server | - Installed on-premises.
 - Can be configured in offline or online mode:
- When in offline mode, functionality is the same as CAST Extend Offline and extensions must be added manually to CAST Extend Proxy.
 - When in online mode, CAST Extend Proxy is configured to connect with CAST's Extend system for Extension management over the public internet.
 
  - AIP Console connects directly to fetch required extensions.
 - Configured in AIP Console in the start-up wizard.
