/**
* @file Enum_Interfaces_Test.cpp
*
* 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.
