rather than pollute the post with the std guff, I have a generic question for now.
When requesting a multi-named cert (not a wildcard cert), i.e. each extra name a sub-domain for the main domain request (e.g. alphabet.com, abc.alphabet.com, def.alphabet.com, xyz.alphabet.com), does Let's Encrypt require each of those sub-domains to have public DNS records or ...?
I would expect not, but .....
I want to be able to use the same cert for hosts with public names as well as internal names.
