Registrar DNS is the free DNS hosting that comes with your domain. Managed DNS is a dedicated service built for speed, uptime and security, usually on a global anycast network. Small sites can live on registrar DNS. Businesses that depend on their website, email and apps should use managed DNS.
Here is a side-by-side comparison and a quick guide to choosing.
| Feature | Registrar DNS | Managed DNS |
|---|---|---|
| Cost | Usually free | Paid, often low per domain |

| DDoS protection | Limited | Built in |
| DNSSEC | Sometimes | Usually supported and automated |
| Failover and traffic steering | No | Yes |
| Access control and audit logs | Basic | Roles, approvals, logs |
| API and automation | Limited | Full API |
