My registrar tell me that I can't have a CNAME record that doesn't start with www. Is it true?
So I am using amazon ec2 with load balancing. the loadbalancer has a convoluted DNS name, and specifically tells you to use a CNAME to send requests to that DNS name, and not an A record.
myloadbalancer-1234567890.us-west-1.elb.amazonaws.com (A Record)
Note: Because the set of IP addresses associated with a LoadBalancer can change over time, you should never create an "A" record with any specific IP address. If you want to use a friendly DNS name for your load balancer instead of the name generated by the Elastic Load Balancing service, you should create a CNAME record for the LoadBalancer DNS name, or use Amazon Route 53 to create a hosted zone. For more information, see Using Domain Names With Elastic Load Balancing.
I purchased a domain. The registrar doesn't allow you to add records yourself, only by emailing them a request. So they set up a CNAME record
mydomain.org SOA 111 whatever www.mydomain.org CNAME 3596 myloadbalancer-1234567890.us-west-1.elb.amazonaws.com
when I asked them why it doesn't work with
www, the registrar answered that there is a technical prohibition to make a CNAME record without
www. Is it true, or are they incompetent/lying and I should switch registrars?
