title: How can I redirect all URLs containing an IP address to my www domain?
body: <p>I have several servers with different IP addresses.  I want to make it impossible to reach them via IP directly.  Instead, I want them to redirect to my domain, www.site.com.</p>
  
  <p>The following condition matches an exact IP:</p>
  
  <pre><code>RewriteCond %{REMOTE_HOST} !^123\.456\.789\.012$
  </code></pre>
  
  <p>How can I match <em>any</em> IP using Apache rewrite rules?</p>
