# Why You Cannot Use a CNAME Record at the Root Domain

The [DNS](https://dotroll.com/en/knowledge-base/books/dns-settings "Category: DNS") administration interface doesn’t allow it to be added to the root of the domain because the CNAME (canonical name) is not only a redirection of the record A, but also the full domain name. If a CNAME record could be created for the domain, it would also move the [NS](https://dotroll.com/en/knowledge-base/books/dns-settings/page/what-is-an-ns-name-server-record) and [SOA](https://dotroll.com/en/knowledge-base/books/dns-settings/page/what-is-an-soa-record-in-dns) records elsewhere, which would be equivalent to making the domain unusable.
