Thanks for the explanation and quick response.

I'm not sure I agree that NOERROR is a valid response if some other record
is queried for. I mean most other implentations do the other thing so even
if this is the correct way, a lot of compatibility is broken, but that is
up to you guys.

This last bit really shows where we went wrong. I'll remember not to use a
wildcard without a proper subdomain (lightly). If I had a wildcard A in the
domain (without subdomain) it would have broken even more by resulting in
the same address for every host tried.
