I did some more digging on this and found this:
"A
CNAME cannot be placed at the root domain level, because the root domain is the DNS Start of Authority (SOA) which must point to an IP address. CNAME records must point to another domain name, never to an IP address."
A Canonical Name (CNAME) Record is used in the Domain Name System (DNS) to create an alias from one domain name to another domain name.
ns1.com
So while it should *technically* be possible to have this be the only record, as long as an SOA exists, which is required in every DNS zone, this isn't going to be possible.
So no, it doesn't look like this is possible.
It would be better to setup a website and redirect that to the specific page or domain you want.
