I do not have or want a custom domain, but I wonder if it is possible to add DNS records to the default netlify subdomain?

I know that this is possible with custom domains on the “Domains” tab, but I do not find where to add a DNS record in a website that doesn’t have a custom domain.

thanks

@angelGRivas As far as I know, this is not possible. Just out of curiosity, what kind of DNS records would you add?
