I’m attempting to complete the setting up of cerbot I can not modify DNS records from CLI but I have access to modify records from my client area I just wanted to know what dns cname I need to create based on the command line I’ve provided your help would be greatly appreciated
There's so much wrong here that I really don't know where to start, but this isn't a command. It's not something you'd run. It's a version of a DNS record, but you don't give any indication of why you'd want that DNS record, why you're trying to use acme-dns, or why (if you are using acme-dns) you aren't hosting it yourself.
What instructions are you following? Because either they're very poor instructions, or you're misunderstanding them pretty badly.
