My current DNS configuration has the blank hostname as well as
www going to the VPS's IP address, and they're being served up fine.
Is there anyway to specify that any other subdomain (is that the right word) like foobar.mydomain.com goes to a particular IP?
I'd like to do this so I can add new subdomains on the fly through Apache rather than having to explicitly declare it in the DNS entry, which is my current option. Are there any major reasons why I should avoid this wildcarding?
