I'm tired of typing manage.py startserver 10.211.55.4:4000, so decided to make an alias for that. Only thing is: the port sometime changes. So I did this in bash profile:

function runserver() {
   python manage.py runserver 10.211.55.4:$1
}

But then when I call it: runserver 3000, it starts it, but immediately stops saying:

"Error: That IP address can't be assigned-to". However if I type the same thing right into command line it works with no complains.
