Displays information about security parameters that were specified with the SET COMMUNICATION command.
Displays the information in the configuration database. This database, read by the TCP/IP Services startup procedure, holds information to:
- Configure the lower-layer protocols, including dynamic routing.
- Configure and enable the Internet interfaces.
- Configure the services you want enabled when TCP/IP Services starts up.
- Configure the BIND resolver.
- Configure the BIND server, including the default domain.
- Configure SMTP.
- Configure SNMP.
- Configure TIME.
- Map file systems.
Because the SET CONFIGURATION commands do not take effect until the next time TCP/IP Services starts up, the SHOW CONFIGURATION command might not display the current settings for the running software. For example, the information you see from SHOW CONFIGURATION PROTOCOL might differ from the SHOW PROTOCOL /PARAMETERS output.

- If a host has more than one IP address and you specify the name, all IP addresses and aliases for the host are displayed.
- If a host has multiple IP addresses and you specify an alias that is defined on multiple IP addresses, only the first IP address and aliases are displayed.
- Recommended: Use the host parameter instead of this qualifier.
/DOMAIN=domain
Optional. Default: Name service domain.Domain to be used by the local host. However, the definition of the domain name is valid only during the execution of the current SHOW HOST command. The BIND request is sent to the specified domain.

/OUTPUT=file
Optional. Default: Screen display.Specifies a file for the output of the SHOW HOST command.
/SERVER=server
