title: Blocking all of tumblr from hosts file
body: <p>I am trying to block tumblr, and all it's pages, using my hosts file. Usually I would just add an entry like </p>
  
  <pre><code>127.0.0.1 tumblr.com
  </code></pre>
  
  <p>to my file, but tumblr has websites in the format " sitename.tumblr.com"</p>
  
  <p>I have tried </p>
  
  <pre><code>127.0.0.1 *.tumblr.com
  127.0.0.1 http://*.tumbr.com
  </code></pre>
  
  <p>And neither work either. Does anyone know how to block tumblr without installing bulky software?</p>
