//
// = 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.
