address is for a host or network.
Format:
SHOW ROUTE /ADDRESS=internet_address
For UCX V1.3 and later releases, this qualifier is not necessary.
/FULL
Specifies that the association of: destination name and address, and gateway name and address is to be displayed. A prefix of "*" on the the Internet address means that the route was specified by address instead of by name. If a host is multi-homed, and the Internet software is not active, then the Internet address for the named host will not be resolved. In this case, the address is displayed as "?".
