Hi members,

I know wildcard can be setup for A,AAAA,MX etc.
But following this thread,

wildcard seems should support CNAME too.

if I setup this:

*.example.com.  CNAME  wild.example.net.
*.example.com.  MX     mail.example.net.
www.example.com  A

When we query for "www.example.com A" or "www.example.com MX",  since 
there are CNAME exists,they may get conflicted, we won't get the correct 

So we shouldn't setup wildcard for a CNAME. am I right?
