I started Amazon EC2 instance, installed rails environment and succeeded running my rails app.
I wanted to direct a subdomain to that instance. My domain registrar is Godaddy. So, sub.example.com should point to my instance.
So, (1) I attached an elastic IP to my Amazon instance. (2) Added an A record to the Amazon Route 53 Hosted zone for my domain, connecting Elastic IP and the subdoman. For the next step I tryed to enter domain server records from delegation set of Route 53 to Godaddy Zone file. But I couldn't manage to do that. Then I just added A record and pointed sub.example.com to the Elastic IP.
My question, is there a way to use those delegation sets in Godaddy? Or maybe there are for something else?
Also, I found this http://support.godaddy.com/groups/domains-management-and-services/forum/topic/delegated-subdomain/ Maybe it is impossible to use NS records for subdomains. By the way, sub.example.com is redirecting to Amazon instance, what I did in Godaddy console works.
Thank you very much!
