Goodness gracious, I often have multiple names for the same IP address.
I also have multiple addresses for the same name.

CNAME is mostly useful for special host services that move around from
time to time.  So, you change easily change ftp.foo.bar from
here.foo.bar to there.foo.bar.  There is no FX record for FTP, POP, WWW,
etc, etc.

CNAME isn't a good substitute for MX records, which are a nice special
case.  CNAMEs can't have any _other_ kind of record.  So, if you use
multiple addresses as you have, you could have one set of MX records for
domain.name, and another MX record for hostid.domain.name.  Beefs up
robustness.
