In C# what does it mean to get a System.Exception: IP Out Of Range?
<p>When attempting to use <code>HttpClient</code> to post async I received an aggregate system exception that included the error <code>System.Exception: IP Out Of Range</code>. I am able to make the same call from a different machine without issue, what would cause this?</p>

<p>Note that the IP address is being resolved through the DNS, a url is provided to the function.</p>
