title: MySQL Warning: IP address could not be resolved
body: <p>I just noticed this warning in the MySQL Workbench log:</p>
  
  <p><strong>[Warning], IP address '112.30.xxx.xxx' could not be resolved: This is usually a temporary error during hostname resolution and means that the local server did not receive a response from an authoritative server.</strong></p>
  
  <p>What does it mean?  I have the MySQL port firewalled so that any incoming TCP traffic is blocked.  Any ideas where this is coming from?  How to I eliminate the warning?</p>
