+<strong>Syntax:</strong> HostNameLookups <em>boolean</em><br>
+<strong>Default:</strong> <code>HostNameLookups on</code><br>
+<strong>Context:</strong> server config, virtual host, directory, .htaccess<br>
+<strong>Status:</strong> core<p>
+
+This directive enables DNS lookups so that host names can be logged.
+Having this directive set <code>on</code> also enables the use of names
+in &lt;Limit&gt; blocks for access control.<p>
+
+Heavily loaded sites should set this directive <code>off</code>, since DNS
+lookups can take considerable amounts of time. The utility <i>logresolve</i>,
+provided in the <i>/support</i> directory, can be used to look up host names
+from logged IP addresses offline.<p><hr>
