be told to listen on specific ports, or only on selected
addresses, or a combination of both. This is often combined with the

<code>httpd</code> responds to different IP addresses, hostnames and
ports.</p>
<p>For example, to make the server accept connections on both
port 80 and port 8000, on all interfaces, use:</p>
- <div class="example"><p><code>
- Listen 80<br />
- Listen 8000
- </code></p></div>
+ <pre class="prettyprint lang-config">
+Listen 80
+Listen 8000
+ </pre>

<p>To make the server accept connections on port 80 for one interface,
and port 8000 on another, use</p>
- <div class="example"><p><code>
- Listen 192.0.2.1:80<br />
- Listen 192.0.2.5:8000
- </code></p></div>

+Listen 192.0.2.5:8000
+ </pre>

<p>IPv6 addresses must be enclosed in square brackets, as in the
following example:</p>
- <div class="example"><p><code>
+ <pre class="prettyprint lang-config">
Listen [2001:db8::a00:20ff:fea7:ccea]:80
- </code></p></div>
+ </pre>

<div class="warning"><p>Overlapping <code class="directive"><a href="./mod/mpm_common.html#listen">Listen</a></code> directives will result in a
fatal error which will prevent the server from starting up.</p>

following examples:</p>
- <div class="example"><p><code>
- Listen 0.0.0.0:80<br />
- Listen 192.0.2.1:80

<p>You only need to set the protocol if you are running on non-standard
ports. For example, running an <code>https</code> site on port 8443:</p>
