python manage.py runserver 0.0.0.0:8000

Changing the port

By default, the runserver command starts the development server on the internal IP at port 8000.

If you want to change the server's port, pass it as a command-line argument. For instance, this command starts the server on port 8080:

python manage.py runserver 8080

If you want to change the server's IP, pass it along with the port. So to listen on all public IPs (useful if you want to show off your work on other computers), use:

python manage.py runserver 0.0.0.0:8000

Full docs for the development server can be found in the runserver reference
