title: Block specific IP block from my website in PHP
body: <p>I'd like, for example, block every IP from base 89.95 (89.95.<em>.</em>).
  I don't have <code>.htaccess</code> files on my server, so I'll have to do it with PHP.</p>
  <pre><code>if ($_SERVER['REMOTE_ADDR'] == &quot;89.95.25.37&quot;) die();
  </code></pre>
  <p>Would block specific IP. How can I block entire IP blocks?</p>
