title: How do I find my computer's IP address using the bash shell?
body: <p>Every now and again, I need to start the Django development server, and have it viewable by other machines on my network, as described here:</p>
  
  <p><a href="http://docs.djangoproject.com/en/dev/ref/django-admin/#runserver" rel="noreferrer">http://docs.djangoproject.com/en/dev/ref/django-admin/#runserver</a></p>
  
  <p>My machine’s IP address tends to change every now and again, so I’d like to have a little shell alias or something that spits out the manage.py command with my machine’s current IP address, maybe like this:</p>
  
  <pre><code>python manage.py runserver $(COMMAND TO FIND MY MACHINE’S IP ADDRESS GOES HERE):8000
  </code></pre>
