A CNAME record creates an alias, which means that all the records for that
name are automatically retrieved from another name.  An A record just maps
a name to an address.  In most cases, CNAME records are the way to create
aliases like want.  However, there are some restrictions on CNAME records,
and in those cases you would have to use multiple A records that have the
same address.  The restriction that might affect you is that a CNAME can't
have records of its own, so if you're trying to use the bare domain name as
an alias, it must be an A record (because the domain name by itself will
have SOA and NS records).
