Q: 

should wildcards belong to CNAME or A NAME?

should wildcards belong to CNAME or A NAME? Both looks the same to me, and googling gives me a inconclusive result.

Any rational and implications behind for choosing one over the other? (underlying DNS server software? web hosting software? speed?)

+1  A: 

I don't think it practically matters.

A wildcard can be used for any DNS record type, so it's not a wildcard for *.domain it's a wildcard only for the particular record type.

RFC 4592 covers them in extreme detail.
