Should I use an A record or a CNAME for a wildcard subdomain?

subdomain, wildcard-subdomain

Solution

It won't really matter if you `CNAME` or `A` record the `*.example.com` record.

The one benefit to `CNAME` is that if you change your `A` record for `www.example.com` you won't need to change the `*.example.com` record as well, but that's minimal.

Problem

Some people are saying use an A record and others a CNAME for a catch all subdomain. Which should I use and why?
