++ <p>The <code class="directive">ListenFree</code> directive is
++ identical to the <code class="directive">Listen</code> directive.
++ The only difference is in the usage of the IP_FREEBIND socket
++ option, which is enabled by default with <code class="directive">ListenFree</code>.
++ If IP_FREEBIND is enabled, it allows httpd to bind to an IP
++ address that is nonlocal or does not (yet) exist. This allows httpd to
++ listen on a socket without requiring the underlying network interface
++ or the specified dynamic IP address to be up at the time when httpd
++ is trying to bind to it.
