Is a DNS root record required?

I am hosting a site off of Amazon S3 and hence can't point the root record, ie: domain.com to an Alias. The www.domain.com points to the S3 endpoint.

Do I have to have a root record and does it have to be an A record?

Root records in DNS are the central DNS servers the world relies on to coordinate resolution. This has nothing to do with your server or DNS records.

I think what you're looking for is a Default Record, so that when people go to http://domain.com it brings up your site. Yes, Default Records have to be of type A (or AAAA for IPv6 addresses) in most DNS servers.

There is a restriction that CNAMEs, which are the aliases, are only allowed to be by themselves and thus aren't allowed as a top-level domain record (because there is also an SOA record there). So, no you can't have an alias. But functionally a web browser will treat a CNAME and an A name the same way so it wouldn't help you in the end.

Your problem is that you need a web server to be running and acting as domain.com and then redirecting you to www.domain.com. That's actually what I'd suggest and what many sites do: The server that serves up this redirect doesn't need to be nearly as beefy as the www one.
