Can I use CNAME with root domain?


Is there something wrong with using CNAME with root domain?
When I use CNAME with root domain it give me error like tihis:

CNAME Flattening will be applied to this record since root (i.e. apex) CNAME records are limited by the DNS specification.

Is CNAME with root domain cause any problem?

Yes, you cant create a CNAME for it. Cloudflare works around that by flattening it into an A record.


For url forwarding I must add CNAME with root domain. Is this cause any problem. For example email delivery or something else? I am use cloud server.


Usually: yes it could lead into problems. But Cloudflare wouldn’t be Cloudflare if… nah… Read this :slight_smile:
