Tony,
I failed to mention that; but in the scenario provided, it was
referencing an Internet host (IP address needing a FQDN). And you are
correct, a CNAME should (in good practice) only point to an A Record.
While it can point to another CNAME, you increase the chance that it
will not resolve, or that an unresolvable loop is created.
