Hosts file missing?

Hello,

I am trying to find my hosts file on Mac OS X Lion (10.7.1) but can't find it. I am trying to modify it so that I don't have to wait to see updates to my site if I change the DNS settings.

When I search for it, I can find a file called hosts in /Developer/usr/etc/distcc but I am not sure if thats the correct file as many sites say to look in etc/hosts in Macintosh HD. Is this the same hosts file?

Regards,

Tim
