It's perfectly fine for localhost to resolve to the machine's external
ip address. It would be weird for it to resolve to some other host's
ip address like the vm's host machine. But having 127.0.0.1 not exist
would be positively broken. All kinds of things wouldn't work. Are you
sure about that part?
