I want to change A record of my root domain www.domain.com to CNAME dyndns.org

But cpanel gives me error:

already has a SOA record.
You may not mix CNAME records with other records for the same name.

Can you please explain what this means? and how do I fix it?

Just to clarify, www.example.com is not the root of the domain, example.com is.

A CNAME on www.example.com is valid, but a CNAME on example.com is not - cpanel is right to reject the attempt. A CNAME record can only exist on a name when no other record type exists for that name, since it indicates that all lookups (of any type, not just A) for that name should look up against a different name instead. You must always have at a minimum an SOA record and an NS record on your root name (example.com), so a CNAME conflicts with the existence of those records.

to overcome this problem, can I CNAME www.example.com to dyndns server, and in some way redirect example.com to www.example.com ? –  Sandro Dzneladze Jul 10 '12 at 21:38
@SandroDzneladze Yes, but that depends on having a mechanism to perform the redirect. Do you have a web server available that can be pointed at through an A record, which can then redirect to the www name? –  Shane Madden Jul 10 '12 at 21:41
yes I have hostgator account where I'm setting up cname records to point to my homeserver with dynamic IP. What would be google safe way of redirecting example.com to www.example.com? –  Sandro Dzneladze Jul 10 '12 at 21:43
@SandroDzneladze A 301 redirect is the search friendly way to do that; it informs the search engine that the redirect is "permanent". –  Shane Madden Jul 10 '12 at 21:50
Thanks! you have been very helpful :) –  Sandro Dzneladze Jul 10 '12 at 22:03
