requests for the hosts. This is configured using the <code class="directive"><a href="../mod/core.html#namevirtualhost">NameVirtualHost</a></code> directive.
In the normal case where any and all IP addresses on the server should
be used, you can use <code>*</code> as the argument to
- <code>NameVirtualHost</code>. Note that mentioning an IP address in a
- <code>NameVirtualHost</code> directive does not automatically make the

<p>The next step is to create a <code class="directive"><a href="../mod/core.html#virtualhost"><VirtualHost></a></code> block for
each different host that you would like to serve. The argument to the
- <code><VirtualHost></code> directive should be the same as the
- argument to the <code>NameVirtualHost</code> directive (ie, an IP
