Third/fourth/etc-level domains and wildcards

If this is mentioned somewhere I apologize. This is related to wildcards. From what I understand, they cover *, which translates to third-level domains. And is not covered.

So my question is, will a wildcard cover text only, or also “deeper” subdomain? As in you’d need to add double wildcards for it to work, if that is possible.

I hope this is understandable, please do tell if not.

Yes, you need to add multiple wildcard identifiers to cover multiple levels.


-d "*" -d "*" -d "*"

However, wildcards must only occur as prefixes. The following are impossible:

-d "*.*"

-d "app.*"

Okay! Thank you for the quick and detailed answer.
