title: Why does the MySQL built-in function 'current_user()' return a hostname containing a '%' symbol?
body: <p>Does MySQL have built in function to get host name?</p>
  
  <p>Similar to </p>
  
  <pre><code>select user(); //this returns  user@userip
  </code></pre>
  
  <p>Edit:</p>
  
  <pre><code>select current_user(); //returns user@10.0.3.%
  </code></pre>
  
  <p>Last symbol is <code>%</code> -- why?</p>
