Asked by seantansey
I would like to set up my web app to use the www subdomain as my primary url. I’ll be using a separate service to handle 301 redirects from apex domain to www subdomain (example.com -> www.example.com). What is the correct way to set up the DNS records for my www subdomain? Should my subdomain have “A” and “AAAA” records pointing to the IP address set up for my naked/apex domain? Or should my subdomain be a “CNAME” pointing to the starter domain generated by my app? (ex. example.test.ondigialocean.app)

Hi there,
What you would need to do is to first add your subdomain name as a custom domain name for your App as described here:
https://docs.digitalocean.com/products/app-platform/how-to/manage-domains/
And then, as you mentioned you would need to add a CNAME record for your subdomain name to point to the App hostname.
Note that, after the DNS change it could take up to a few hours for the DNS cache to clear over the Globe before you could see the new record:

Hope that this helps!
Best,
