Does the hosting uses wildcarded dns? or not
Does it use it, or do we support it? Basically, the answer is "no" for both.
Is there any way you could add that function? It can be very useful at times, like when you want to add generic redirections of any subdomain name somebody might type to queries into a search script, for instance.
I could probably add one (by hand) in a specific case, but there are no plans to add this functionality. In the past, this was mostly because we didn't offer unlimited subdomains.
