cname

I'd like all subdomains that aren't being used for anything else to go straight to my domain.

ns1.mydomain.com.   A   198.123.44.55
ns2.mydomain.com.   A   198.123.44.66
*.mydomain.com. CNAME   mydomain.com
webdisk.blog.mydomain.com.  A   198.123.44.55

However, say I have subdomain blog.mydomain.com which I still want to behave as a normal subdomain. I would like the following to happen:

     mydomain.com -->      mydomain.com
 www.mydomain.com -->      mydomain.com
 abc.mydomain.com -->      mydomain.com
blog.mydomain.com --> blog.mydomain.com

Is this possible?
