When creating CNAME Records, please note:

  • If "Wildcard Alias" is enabled for your domain name in the control panel, all aliases unless otherwise specified point to your primary domain IP address. For example, www.yourdomain.com, ftp.yourdomain.com, mail.yourdomain.com automatically point to the 'A' record of your primary domain name yourdomain.com. There is no need to set a CNAME record for that.
  • CNAME records for root domain are invalid based on DNS RFC’s. If you want your domain name yourdomain.com point to some other site, you may use "URL Forwarding" function in Dynamic DNS Service Web Redirect Web Redirect.

To point all your subdomains to your primary domain, you can enable "Wildcard Alias" for the domain name. All subdomains will automatically redirect to your primary domain. Please note that each separately configured subdomain (either with an A record or a CNAME record) has priority over the wildcard configuration.
