Cart redirecting to the IP - config setting?

When I installed the site I used an IP because the site was in testing. Now that the site is live I can’t figure out how to change it back to a regular www. This makes it impossible for anyone to checkout securely. When they go to any page it is redirecting them to the IP based (I’m guessing) on the config settings, and I can’t find out how to change them.



WHY IS THIS SO HARD TO FIND?



I have looked in the admin area under setting and even tried sifting through database tables.



I am so dead right now. PLEASE ANYONE HELP.

Edit config.local.php
