Reading through the Netlify documentation, it seems to suggest that it cannot be both a CNAME and an A record, but just one or the other:
Configure an apex domain
Unlike subdomains, apex domains don’t support CNAME records. The standard alternative, an A record , points to a single server IP address, which means it can’t take advantage of direct DNS routing on a global CDN like Netlify’s.
Some DNS providers, such as Netlify DNS or NS1, have devised special record types to simulate CNAME-style domain resolution for apex domains. Find out if your provider supports this type of behavior, which might be labeled as CNAME flattening, ANAME records, or ALIAS records.
If your DNS provider supports one of these special record types (recommended), find and follow their instructions to point the apex domain directly to your Netlify subdomain, such as
If your DNS provider does not support CNAME-style resolution for apex domains , you must configure your domain with a single-server A record:
