I recently had an issue with a website not working because it wasn't resolving the www subdomain correctly. The issue was the lack of a dot (.) at the end of the domain name for the CNAME record.
Some DNS providers don't require a dot at the end (or they auto manage it in the background) -for example Cloudflare- and that makes this a little more confusing for the client, and mistakes can be made.
Is it a way to automatically determine when a dot is needed and add it? Or manage it in the background?
