//
// = DESCRIPTION
//     This is a simple test of <ACE::get_ip_interfaces>.  This call
//     retrieves the IP addresses assigned to the host by
//     interrogating the kernel.  Network applications typically
//     assume gethostbyname(uname()) will work, but this is just a
//     convention. It is also problematic if the resolver code
//     (DNS/NIS+...) is misconfigured. This happens more than
//     programmers realize. It is better to find out by asking the
//     kernel for local address assignments. This API is similar to
//     what netstat -ni or ifconfig -a produces on UNIX or ipconfig on
//     Windows NT. In fact, it was by reverse engineering these tools
//     that this api was created.
