I don't know DNS, and need to make a request. However, I want to make sure I don't hose our services when someone does what I ask.
Suppose we have an entry such that
*.bar.com resolves to some IP
I want another entry
*.foo.bar.com to resolve to a completely different IP
Can I do this, or will the entry for *.bar.com trump the entry for *.foo.bar.com rendering the entry I want useless?
