I recently moved some domains to a DirectAdmin server, and the DNS stuff was already set up for me. However I'm wondering about subdomain DNS records.
There are A and MX and NS records for the main domain, e.g. "example.com." (including point at the end) and also a bunch of common subdomains, like www, ftp, mail, and so on.

But shouldn't that be "www.example.com." and "mail.example.com." etc? Or are partial names (just the subdomain part like "www") automatically interpreted as "www.example.com." ?
Also, if I want to add a wildcard subdomain record, so that <anything>.example.com resolves to example.com, should I add an entry like this:
