>The short solution is, instead of using yourdomain.com, use www.yourdomain.com. Then, redirect the root domain to the www subdomain using a DNS CNAME record.
The root can't be a CNAME because no other record with the same name aside of a CNAME can exist. Your domain root also has one SOA and two NS records (and probably one more more MX records if you want to receive mail)
