Clarification on wildcard scenario

Tue Feb 1 04:37:37 UTC 2011

I must admit, I'm kinda confused by what you are actually trying to achieve....

?A foo.joshfeb1.com. should be getting returning 1.1.1.1

?A www.joshfeb1.com. should be returning noerror / nodata because:
1: There is a record at www.joshfeb1.com (so it's not NXDOMAIN), but
2: the record is not an A record (so there is NO DATA that matches)

I'm assuming if you query for A foo.www.joshb1.com. you get back 2.2.2.2?
