wildcard

[Frank Liu]

I am reading RFC 1034 Section 4.3.3 about wildcard in DNS.

    *.X.COM         MX      10      A.X.COM
    A.X.COM         A       1.2.3.4
the second entry in the zone file will inhibit the subtree of A.X.COM
and we will have to add
    *.A.X.COM       MX      10      A.X.COM
again.

My question is 
will "D.C.B.A.X.COM A 1.2.3.4" inhibit subtree of A.X.COM from *.X.COM?
I tried this with Bind-8.2.2P5 and the answer is "yes". I am not
sure if this is a bug or a feature.

Thanks!

Frank
