command prompt to verify DNS resolves or IP address valid

Command line utility (unmanaged C++, Visual Studio 2008) which takes one parameter, which is either a DNS name or an IP address (similar to how PING accept a single parameter). It verifies that it is correct and shows "OK", or returns an error message "ERROR: <error message>". If the parameter was an IP address, verify it's a valid IP address (i.e., defined as public or private IP, not something out of legal range like 0.0.0.0). If it is a hostname, it should resolve to IP using DNS lookup. The program should be structured so there is a function/method that takes a single string parameter and returns a boolean result; and another function to retrieve the error string if the result was false. ## Deliverables Visual Studio 2008 C++ MFC Command line command Must run successfully in Windows XP through Windows 8, and Windows Server 2003 through Windows Server 2008 R2.
