I recently bought three domains via some site, planning on pointing them to an S3 bucket.
The first one I succeeded in doing so, because I added both name servers, an A record, and a CNAME for the subdomain (www). Those I got from Amazon Route 53 (I added A record and CNAME myself).
The others I can't get to work, simply because the domain registrar site won't let me change anything but the name servers (don't ask me why).
My question: are or aren't the name servers enough to point a domain in the right direction? Is it impossible to host a site on an S3 bucket with my own domain with only access to name servers?
