 DNS records contain information about your domain and are used to make your website or application available to visitors and other web services.
 
+Depending on the providers you used to [get your domain name](/fundamentals/setup/manage-domains/#get-a-domain-name) and [host your website or application](/fundamentals/setup/manage-domains/#host-your-domain), it is expected that DNS records were automatically created on your behalf. As an [authoritative DNS provider](/fundamentals/concepts/how-cloudflare-works/#how-cloudflare-works-as-a-dns-provider), Cloudflare can help you manage your DNS records.
