I see dustafo, the brilliant web designer/computer programmer, missed his class about how to bypass incorrect DNS.
 
If using Windows XP/Vista (There are ways on any operating system, but I use XP and Vista, so someone else can fill that in): 
Go to [System Root]\WINDOWS\system32\drivers\etc 
Open the file called hosts(no extension) in notepad. 
At the bottom add one of these lines,not both, and save:  
 Code:
 209.237.228.138  bitzi.com
209.237.228.138  www.bitzi.com
  Restart your browser 
BTW, this should even work for Limewire bitzi lookup, at least it does for several other better programs. To be honest, I don't use Limewire.
