Do it with A records, not CNAME records.  At best, a domain name pointing to
a CNAME will not be allowed by your DNS server (I think some RFC explicitly
forbids this).  At worst, you will get weird results.

Back when CCCD first went online, I tried to make cccd.edu point to a CNAME
and it definitely didn't work:

spock.dis.cccd.edu.     IN      A       159.115.1.5
cccd.edu.               IN      CNAME   spock.dis.cccd.edu.
www.cccd.edu.           IN      CNAME   spock.dis.cccd.edu.

So then I switched it to the following and everything is happy:

spock.dis.cccd.edu.     IN      A       159.115.1.5
cccd.edu.               IN      A       159.115.1.5
www.cccd.edu.           IN      CNAME   spock.dis.cccd.edu.
