<A name="hostnamelookups"><h2>HostNameLookups directive</h2></A>

<!--%plaintext &lt;?INDEX {\tt HostNameLookups} directive&gt; -->

<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>
