Domain forwarding in AWS Lightsail

Question

For example, I have a domain named example.com and I want to direct it to my subdomain such as info.example.com. I'm trying to add a CNAME record for this from the DNS zone section, but I'm getting an error.

Answer

Hello,

CNAME records cannot be configured at the top node (or zone apex) of a DNS namespace.

From Route 53's documentation:
> The DNS protocol does not allow you to create a CNAME record for the top node of a DNS namespace, also known as the zone apex. For example, if you register the DNS name example.com, the zone apex is example.com. You cannot create a CNAME record for example.com, but you can create CNAME records for www.example.com, newproduct.example.com, and so on.

I've included links to documentation below, including a link to a community-provided historical context of CNAME records:
* [Route 53: CNAME Record](https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/ResourceRecordTypes.html#CNAMEFormat)
* ["Why can't a CNAME record be used at the apex (aka root) of a domain?"](https://serverfault.com/questions/613829/why-cant-a-cname-record-be-used-at-the-apex-aka-root-of-a-domain)
