Consider the following points before using the HOSTENT utility:
PowerExchange uses the TCP/IP resolver to translate the host name of the TCP/IP stack into an IP address.
On z/OS and OS/390 the resolver queries the local host table. On i5/OS, Linux, and UNIX, the resolver queries the name server before it queries the local host table.
On i5/OS, z/OS, and OS/390, PowerExchange uses the primary interface address of the TCP/IP stack to verify the licence if the resolver cannot find the host name.
Operating systems can run more than one TCP/IP stack. Ensure that the HOSTENT runs on the TCP/IP stack that is used by PowerExchange. You cannot specify a stack name in the HOSTENT parameters.
