Google domains’ DNS doesn’t support ALIAS/ANAME record to apex domain (also naked domain), but it supports domain forwarding to a subdomain from an apex domain.
Let’s set this up.

In this example, we use the following records as a sample:

• Domain: example.com 

• Subdomain: www.example.com 

• Shifter URL: abc123.on.getshifter.io 

• CDN Raw Hostname: def456.cloudfront.net  

​

Setting up

1. Log in to the Google Domains Control Panel
2. Navigate to [My domains]
3. Click the [Manage] button on your domain

4. Navigate to [Website] menu

5. Click [Set up forwarding]

6. Set up like below:

a) Input the naked domain name to the “Forward from” field
e.g. example.com

b) Input the URL of the www-prefixed domain name.
e.g. https://www.example.com

c) Click the [Forward] button to save changes

7. Domain forwarding has been added.

That’s all.

Let’s access your naked domain with your web browser and check that the domain is forwarding correctly.

Here is a sample command with a URL and its result:

curl --head http://example.com
HTTP/1.1 301 Moved Permanently
Location: http://www.example.com
