Are there any records (or delegation to subdomain) for
<something>.a.dev, even though a.dev itself doesn't exist explicitly?
If yes, then the wildcard won't provide the answer, because the
existence of <something>.a.dev creates what's called an 'empty non
terminal'. Wildcards only match where the record doesn't exist - but
ENTs do count as 'existence'.
