I am puzzled as to why the following screen-shot displays the IP address  
of localhost as 0.0.0.0 instead of 127.0.0.1?

C:\InstantRails20\rails\_apps\blog\>ruby script/server  
=\> Booting Mongrel (use ‘script/server webrick’ to force WEBrick)  
=\> Rails application starting on [http://0.0.0.0:3000](http://0.0.0.0:3000)  
=\> Call with -d to detach  
=\> Ctrl-C to shutdown server  
\*\* Starting Mongrel listening at 0.0.0.0:3000  
\*\* Starting Rails with development environment…  
\*\* Rails loaded.  
\*\* Loading any Rails specific GemPlugins  
\*\* Signals ready. INT =\> stop (no restart).  
\*\* Mongrel 1.1.2 available at 0.0.0.0:3000  
\*\* Use CTRL-C to stop.  
\*\* INT signal received.  
Exiting

It works though. The Rails screen comes up when I type in:

[http://localhost:3000/](http://localhost:3000/)
