About CNAME records
A CNAME record makes one name an alias of another, for example shop.example.com pointing to a hosting provider's hostname. Resolvers follow the chain to the final A or AAAA records.
A name with a CNAME can't have any other records, which is why the bare domain (example.com) usually can't be a CNAME. Many DNS providers offer "flattening" or ALIAS records to work around that.
Frequently asked questions
Can I put a CNAME on my root domain?
Not as a standard CNAME, because the root needs NS and SOA records. Use your DNS provider's ALIAS, ANAME or CNAME flattening feature instead.
