While technically possible in some DNS providers, it's strongly discouraged. Using a CNAME directly on the root domain can interfere with other DNS records like MX records (for email) and can lead to unpredictable behavior. It's best practice to use an A record or an ALIAS/ANAME record for the root domain.
