2  –  Parameters

 host

    Optional. Default: All hosts.

    All alias names for the specified host are displayed.

    o  If a host has more than one IP address and you specify the
       name, all its addresses and aliases are displayed.

    o  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.

    o  If you do not specifiy the host parameter or if you use a
       wildcard, all hosts from the local and BIND databases are
       displayed.

       information is displayed.

3  –  Qualifiers

3.1    /ADDRESS

       /ADDRESS=IP_address

    Optional. Default: None.

    Allows you to select a host by IP address.

    o  If a host has more than one IP address and you specify the
       name, all IP addresses and aliases for the host are displayed.

    o  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.

    o  Recommended: Use the host parameter instead of this qualifier.

3.2    /DOMAIN

       /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.

3.3    /LOCAL

    Optional.

    Limits name-to-address lookups to the local hosts database.

3.4    /OUTPUT

       /OUTPUT=file

    Optional. Default: Screen display.

    Specifies a file for the output of the SHOW HOST command.

3.5    /SERVER

       /SERVER=server

    Optional. Default: Name server list.

    BIND servers to be used. The definition of the server name list
    is valid only during the execution of the current SHOW HOST
    command. The request is sent to the specified server.

    The list is ordered by request preference. For example, the
    initial request is sent to the first host in the list. If that
    host is unavailable, the request is sent to the second host in
    the list, and so on.

    You can specify a maximum of three servers.
