avoid CNAME unless you know you have solid justification.

K I S S.

CNAMEs work fine, but many people don't know the restrictions on CNAME, and screw up their zones.

The basic rules is that a domain name that "owns" a CNAME/alias record cannot own any other record.

A zone name cannot own a CNAME record, because every zone name must OWN at least an SOA record and 1 NS record.

myzone.com. CNAME anything

... is illegal, meaning the common error of:

myzone.com. CNAME yourzone.com.

... is illegal.
