Where would a wildcard DNS record be prioritized?

I have a DNS setup going on where I have several subdomains that cname out to google apps, but I was wondering if I could wildcard the rest of my subdomains, and have my google apps cname correctly. In other words, would the records that aren't a wildcards be parsed before the wildcard record?

  • You'll need to check and see if your DNS host currently supports wildcard subdomains, and if they do, there should be no problems as existing records will be prioritized.

  • As per RFC 1034 sections 4.3.2 and 4.3.3, a wildcard record is always of least priority. Any existing resource records in the same zone are preferred.

    RFC 4592 might also be an interesting read for you.
