I have a domain hosted by Google Domains and have changed the Nameserver to point to Cloudflare. I dynamically update the main domain IP using the suggested Linux utility from a server at home, and the DNS page shows the Type A domain as pointing to the correct IP (TTL is Automatic, and the status is “DNS only”).
I have then created DNS CNAME called (for example) “subdomain”, with a value that says “is an alias of example.com”. The TTL is Automatic, and the Status is set to “DNS and HTTP Proxy”.
The problem is that “subdomain . example . com” (sorry for the spaces, new users can’t put more than two “links” in a post) points to a different IP to “example.com” when I ping it. I’ve left this set up for over 48 hours now as I found other posts that said it needs time to update, but nothing has changed unfortunately.
Does anyone have any suggestions as to what I’m doing wrong please?
