I am currently setting up Magento 2.2 for the company I am working with. I set up most of the things and installed the Magento package on the IP Host. I can access it and it kind of works fine until I go to the admin console. I found out this is happening because there is no SSL assigned to the domain name. However, as I am using an IP I cannot do it. How would I go about assigning a domain name through Ubuntu and DNS? I've pointed some of the A records to the host IP, is there anything else I need to do for this to work?
