Feedback: While the documentation does clearly state that hostname aliases only look up A and AAAA records, it might be helpful to specifically point out that CNAME records aren't resolved. I use DNS aliases only to block IPv6 to a few services who's IPv6 implementation often hiccups, but this is a critical nuance to note if someone were to use them for security reasons.
